• Anstrom (A)
• Picometers (pm)
• Nanometers (nm)
• Micrometers (mm)
• millimeters (mm)
• centimeters (cm)
• decimeters (dm)
• meters (m)
• centimeters meters and meters
• kilometers (km)

• 1/10th of an inch (mil /thou)
• inches (in)
• feet (ft)
• feet and inches
• yards (yd)
• miles (mi)

• nautical miles (nmi)
• Sun radii (R)
• lighting year (ly)
• Astronomical units (au)
• parsecs (pc)

It is an length conversion calculatorworks by entering units (up to 11 in the same calculation) into the calculator. It computes the length converter then returns your results for each unit , in real-time. Choose the unit if you'd like to carry out length conversion to an alternative unit to the ones that are defaulted from to the Omni team. If you're trying to convert between various sizes of area the other option is the

Length conversion table

To find out what conversion coefficients are used for the nine lengths that are the most sought-after length units, read this length conversion table:

We've made a decision to round a few of the variables used in conversion to ensure they fit in this tableau. Therefore, certain values are not exact however, they are still able to provide some degree of accuracy.

Length conversion chart

When you're trying to determine how to quickly change between units within one system look into these two simple length conversion charts:

1. The system of measuring the metric

To give an example:

• 6 km = 6 * 1000 = 6000 m
• 180 cm = 180 / 100 = 1.8 m

1. Imperial US measurements system. US measure system

For example:

• 5 yd = 5 * 3 = 15 ft
• 144 in = 144 / 12 = 12 ft

In addition, we've created an index of the most requested length converters. The most popular ones to look for are:

1. meters to feet / feet-to meters

For those trying to determine how many feet is in a meter you are:

• 1 Meter 3.281 feet which is equivalent approximately 3'3 3/4" and 3'81".
• 1 foot equals 0.3048 Meter

1. cm to inches / inches to cm

Learn the amount of centimeters per inch.

• One centimeter 0.3937 inches
• 1 inch equals 2.54 centimeters

1. feet-to-inchesor inches to feet

To convert between feet and inches use:

• 1 foot = 12 inches
• One in 0.08333 feet 1/12 of one foot

1. feet to yards/ yards to feet

What number of feet could you fit in the backyard? Three!

• 1 yard = 3 feet
• 1 foot 0.3333 yards, 1/3 of one yard

1. feet to miles/ miles to miles

Are you one of those who has wondered how many feet there are in a mile?

• 1 foot 0.00018939 mile
• 1 yard = 5280 feet

Inch definition

The inch (abbreviate as in or ") is an measure of length in the Imperial or US metric system. The term comes from a number of definitions - the length of the human thumb. In certain different languages e.g. Norwegian, Afrikaans, Italian or French the term "inch" is derived from the word"thumb" or in some instances it's the same idea. Since the 14th century onwards An inch was defined as by the King of England to be three grain of barley, dry and round, placed between the ends longways. The definition of an inch changed through the ages but during the 1950's, an international standard was accepted, and since then, the standard of the inch has been exactly 2.54 centimeters.

1 in = 2.54 cm

One inch is also equivalent to one-third of a yard. 1/12 of one foot or 1/63360 of one mile.

On a regular basis inches are commonly used in all of the US, UK, Canada and a host of other countries that were previously as parts of the British Empire. Along with length, width and height can be measured in in different sizes, and also determined by units derived from inches (e.g. shoe size).

What is measured in inches? It's not just in the US but also around the globe?

• screen sizes of monitors, smartphones TVs, and monitors (specifically dimensions of the diagonals of square screens)
• Resolution of screen PPI (pixels per inch)
• size of tires size of tires e.g. car or bike wheels
• diverse equipment and sizes
• Certain sports equipments use the measurement in inches. e.g. for archery.
• in the field of science, e.g. Acoustics are microphones and the sizes of loudspeakers

One International inch is the equivalent to:

• 10,000 tenths
• 1,000 Thou/mil
• 100 points or gries
• 72 PostScript points
• 6 computer picas
• 3 barleycorns
• 2.54 centimeters exactly
• 0.999998 US Survey inches
• 1/3 of which is 0.333 palms
• 1/4 or 0.25 hands
• 1/12, or 0.08333 feet
• 1/36 or 0.02777 yards

Feet definition

The foot (abbreviate as ft, or ') can be described as one of the units of measurement employed within the Imperial or US standard system of measurement. It's a measurement that is based upon the human body as the name implies. The measurement was standardized during the 50s and has been since then it's equal to 0.3048 meters precisely:

1 ft = 0.3048 m = 304.8 mm

The use of feet has been practiced from the beginning of time in various civilisations. However, the size of the foot differed between these different cultures. The foot was utilized, e.g. in:

• Ancient Rome: 1 foot = 11.6 inches (295.7 mm). This was the standard foot, however in some provinces, it may be as large in size as 13.2 inches (334 millimeters)
• Greece: 1 foot = 10.6-13.8 inches (270 - 350 millimeters)
• Indus cities during the Bronze Age: 1 foot equals 13.2 inches (333.5 millimeters)
• Egypt The equivalent is 12 inches (304.8 millimeters)

It is the official imperial but non-official public measurement standards, Greenwich

The measurement of feet is used in England In England the foot measurement has also changed over time - it began in Roman standards, and later Belgic Celts foot of 13.2 inches or Welsh foot was introduced and it was removed. The definition of foot varied from region to region, city to city, then the kings altered the measurements according to their preferences. e.g., Henry I was said to have commanded the creation of a new standard on his arm. Then, Edward II of England introduced an attempt to standardize the foot by introducing the statute foot, which was 10/11 the length of the prior foot. The end of the foot's length was made much later, in the year 1959, following the International yard-and-pound agreement became a reality. Since then, the length of a yard within the United States and countries in the British Commonwealth is equal to exactly 0.9144 meters. When yard was first established in the beginning, feet could be measured as well. This is the equivalent of:

1 foot = (1/3) * yard = (1/3) * 0.9144 m = 0.3048 m

in the US two types of feet are utilized on the regular course of use, which is the international foot, or survey foot.

1. International footAlso called the standard foot, it was first standardized during the 50s. It is widely used in a number of different applications that is the equivalent of 0.3048 m: 1 international foot 0.3048 m . We've chosen the symbol to illustrate is the meaning of this amount. The measurement used in international commerce is the equivalent of the human foot, which has the size of 13 (UK) as well as the size of 14 (US male ).
2. Survey foot The US survey foot is almost identical in measure in size to the base of the world. But the word nearly is the primary . The survey foot definition is precisely 1200/3937 meters. 1 US survey foot = 1200/3937 m 0,30480060960121920243840487680975... m As you can see, this appears like a really tiny difference but something is different when you hit the seventh decimal! This is the difference of only 0,609 millimeters 609 nanometers in comparison to the type of foot you have with the other. Why should we care? Important because the difference is not significant when we're measuring objects that are relatively small, however , the difference is significant when we start measuring hundreds of thousands of feet by mapping as well as using the state plan coordinate system (SPCS). Furthermore, the legislation on the survey foot varies across the 50 states.
   • 24 states have adopted legislation that says that surveying methods should be based on US survey foot. US surveys are based on feet.
   • 8 states have approved the announcement in accordance with the world foot
   • 18 states haven't defined the conversion rate of metric units for 18 states. Don't be concerned all that much if you're need of the conversion for your everyday conveyances or surveys of land, the variation is negligible for short distances (less than 1 mile) and it doesn't matter which definition you choose to use.
   Another measurement of the foot - the Indian survey foot . It's described as precisely 0.3047996 M: 1. Indian survey foot = 0.3047996 m

Feet - as well as the whole imperial system are widespread throughout the US. And almost only there. It's true that the US is regarded as being the one industrialized nation in the world that hasn't yet adopted the International System of Units, also called the system of measurement in units of metric measurement. Two additional countries that employ the system of measurement are Liberia located in Africa as well as Africa as well as Myanmar (also known as Burma) within Southeast Asia. Canadians along with the British make use of a mix of both systems, metric and imperial (e.g. the men's height is usually measured in feet , however inches are also utilized).

Feets are not utilized widely in the non-English-speaking world. The most obvious illustration is the measurement of elevation within the international air travel industry.

Meter definition

Meter (British English: metre) is the basic length unit in several metrics which include those of the International System of Units (SI).

A definition for meter changed with the scientific methods of measuring advanced. The definition now refers to how long is the path that light travels in a vacuum within 1/99,792,458 second.

How was it defined by the time it was first defined?

• The first tests of the definition of meters began in 1790. In 1790, 1790, the French National Assembly decided that the length of the new meter would be equivalent to the length of a pendulum that had one second of a half-period. You can verify the accuracy of this number making use of our calculator for pendulums. Type 2 in the pendulum's time box and you'll then be able to determine the length of the pendulum. In reality, it's very close to the one-meter mark (0.993621 m).

• In 1973 the circumference of Earth was chosen as a neutral reference point. The term "meter" was defined as one-ten-millionths of the distance from the equator to the north pole. North Pole: 1 meter is 1/10,000,000 of the meridional radius of the Earth that is located through the meridian between Earth and Paris
• Between 1799 and 1889, between 1799 and 1889 Between 1799 and 1889, brass, platinum and the alloy of platinum with 10% iridium meter bars were invented, to form a basis having the distance of Earth's meridian. In 1889, the 1st General Conference on Weights and Measures in 1889 defined the meters as the distance that is the distance between two lines on an average bar made of this type of alloy. The International Prototype Meter is still stored within the International Bureau of Weights and Measures in Sevres just outside of Paris. That meter definition was in use until the year 1960 and also the 11th General Conference on Weights and Measures.
• From 1960 until 1983 the meters were redesigned during the decade of 1960. The name was changed to 1,650,763.73 wavelengths of the red-orange radiation Krypton86 under certain conditions.
• 17th Conference defined"meter" to mean 1/299,792,458 of how far light travels within a second. This definition of the meter remains in force up to.

Below is a table that provides the history of a meter's definition (by Cardarelli 2003).

Standard	Date	Absolute error	Relative uncertainty

Imperial / US measurement system

International the US measurement system as in US measurement systems don't have the same characteristics in terms of length measurement, but they're the same (they differ in terms of volume, which means e.g. the cup might contain quantity of floz that differs between the two systems). The only countries that didn't accept measures in metric included those of the US, Liberia and Myanmar.

The six most frequently used US length units (also called imperial length units) were included in our length converter:

• 1,000,000th inch (mil or thou),
• inches (in),
• feet (ft),
• feet, inches and other
• yards (yd),
• miles (mi).

Two more length units, however we have removed them from this length converter on purpose: The term "furlong" refers to the fact that the "furlong"'s conversion ratio is not well-defined and the term league used to be the most widely used measurement in Europe along with Latin America but is no anymore an official unit for any one of them. You can nevertheless find them here, as well as the most commonly used numbers:

Unit	It is similar to the preceding	Feet	Millimeters	Meters
Thous (th)		1/12000	0.0254	0.0000254
inch (in)	1000 Thou	1/12	25.4	0.0254
foot (ft)	12 inches	1	304.8	0.3048

Metric measurement system

The measuring system in metric, commonly called"the International System of Units (SI) has an international decimal-based system for weights and measurements. It is widely used around the world (apart one of the countries mentioned in the earlier paragraphs) It is simple to utilize, practical and rational. The four basic units of the metric measurements are as follows:

• meters ( m) for length,
• kg ( kg) for mass (check out this conversion of weight),
• Second ( s) for time,
• ampere (A) for electromagnetism.

Additionally, 22 derivative units with their own names exist. We can split them into 5 categories:

1. Electromagnetism

• Volt, a measurement of potential electrical
• ohm, a unit of electrical resistance,
• tesla A measure of magnetic flux density
• weber is a type of magnetic flux,
• farad A type of electrical capacitance,

• Coulomb is an expression used to refer to an electric charge.

1. Mechanics

• Watt A element of electrical or mechanical power,
• Newton A unit of mechanical force
• Jourle, a unit of mechanical, electrical or thermodynamic energies
• Pascal is a measurement unit for pressure.

1. Radiofrequency

• becquerel, a unit of radioactive decay,
• Sievert is a term used to describe the absorption of the ionising radiation. You can calculate the radiation dose you received during your journey to the airport with our calculator of radiation for flight,
• grey an element of Ionizing radiation
• Lux can be a word used to refer to luminescent flux
• lumen is an expression used to describe the intensity of luminous light.

1. Circular arches as well as Spherical faces

• The Radian is a type that is a circular arc
