The length converter is a tool that allows quick conversion to length measurements that can be imperial as well as metric. But not only that. It's equipped with twenty dimensions of length:

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

• 1000ths of an inch (mil /thou)
• inches (in)
• feet (ft)
• inches and feet
• yards (yd)
• miles (mi)

• nautical miles (nmi)
• Sun radii (R)
• lighting (ly) (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. The program calculates the length converter then returns your results for each unit , in real-time. Select the unit if you'd like to perform length conversion to an alternative one to the units that are defaulted by the Omni team. If you're wanting to convert between different types of units one option is the

Length conversion table

To find out what conversion rates are applicable to the nine most popular length units, take a look at the following length conversion table:

We've chosen to round a few of the variables used in conversion to ensure they fit in this tableau. Therefore, some values aren't exact however, they are still able to provide some degree of precision.

Length conversion chart

If you're trying to figure out how you can quickly convert between units in one system, take a look at these two easy length conversion charts:

1. The method of measuring metric

To give an example:

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

Inch definition

The inch (abbreviate in the sense of or ") is an measure of length that is used in the Imperial or US standard system of measurement, which is referred to as the metric. The term comes from a few definitions - the width of the human thumb. In certain different languages e.g. Norwegian, Afrikaans, Italian or French the word "inch" is derived from the word"thumb," or in some cases, the same word. Since the 14th century onwards, an inch was defined by King George V of England as three grains of barley which were dry and round, placed between the ends longways. The definition of inch varied over the ages but during the 1950's, an international standard was accepted, and, ever since, the inch is equal to exactly 2.54 centimeters.

1 in = 2.54 cm

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

Everyday, inches are used extensively in many countries, including the US, UK, Canada and a host of other countries which were once part of the British Empire. Along with width, length and height are measured in different sizes, and also determined by units which are derived from inches (e.g. shoe size).

What can be measured in inches? Not just in the US however, but around the world?

• screen sizes of monitors, smartphones televisions, (specifically dimensions of diagonals in the rectangular screen)
• resolution on the screen PPI (pixels per inch)
• dimensions of tires - e.g. car or bike wheels
• various instruments and pipe sizes
• Certain sports equipments utilize the measurement in inches. e.g. for archery.
• in science, e.g. Acoustics -- microphones and the sizes of speakers

One International inch is the equivalent of:

• 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 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 word foot (abbreviate as ft, or ') is one unit of length utilized to measure length in the Imperial or US standard system of measurement. It's an measurement based upon the human body as the name suggests. The measurement has been standardized in the 50s and since then it's equal 0.3048 meters exactly:

1 ft = 0.3048 m = 304.8 mm

The use of feet was used since ancient times throughout different civilizations , but the size of the foot varied between these cultures. The foot was used, e.g. in:

• Ancient Rome: 1 foot equals 11.6 inches (295.7 millimeters). This was a standard foot but in some provinces it could be as wide than 13.2 inches (334 mm)
• Greece: 1 foot = 10.6-13.8 inches (270 - 350 millimeters)
• Indus cities in the Bronze Age: 1 foot equals 13.2 inches (333.5 millimeters)
• Egypt is equivalent to 12 inches (304.8 millimeters)

The measurement of feet in England In England, the foot measure was also altered over the years and began to change in Roman standards and was later changed to Belgic Celts foot of 13.2 inches or Welsh foot was introduced, and was later removed. The definition of feet varied in different regions, and city to city, and then the kings altered the measurements according to their desire - e.g., Henry I was said to have ordered a new standard based upon his arm. After that, Edward II of England introduced some kind of standardization by introducing the statute foot that was 10/11 of the previous foot. The end of the foot's length was reached much later, in the year 1959, shortly after the International yard-and-pound convention had been signed. Since then, yard length in the United States and countries in the British Commonwealth is equal to exactly 0.9144 meters. When yard was first established, the foot could be calculated in the same way. This is equivalent to:

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

The US two kinds of feet are used in regular intervals, that is the international foot, as well as the survey foot.

1. International footAlso known as the standard foot, it was first standardized in the 1950s. It's widely used in number of different applications it's the equivalent of 0.3048 meters: one international foot 0.3048 millimeters and we've used the symbol to convey is the meaning of this quantity. The international measure is the equivalent of a human foot with 13 inches (UK) and 14. (US male ).
2. Survey foot The US survey foot is virtually identical to the bottom of the globe. But the word nearly is the primary . The survey foot definition is precisely 1200/3937 metres 1 US survey foot = 1200/3937 m 0,30480060960121920243840487680975... m As you can see, this appears like a really tiny difference the moment you hit the seventh decimal! It is less than 0,609 mm, 609 nanometers in comparison to the type of foot you have with the other. Why should we care? important because the difference is minimal when we are measuring very small objects but it becomes significant when we begin measuring hundreds of thousands feet by mapping as well as using the state plan coordinate system (SPCS). Furthermore, the legislation on the survey foot is different across all 50 states.
   • 24 states have enacted legislation that says that surveying methods should be built upon the US feet of the survey. US Survey feet are the foot that is used for surveying.
   • eight states approved the announcement in accordance with the world foot
   • 18 states haven't specified the conversion rate for metric units. But do not fret all that much if you're necessity of the change for your routine conveyances or surveying of land. The differences aren't much of a concern for shorter distances (< 1 mile) and it doesn't matter which definition you decide to go with.
   There's another measurement of the foot, namely the Indian survey foot . It's described as precisely 0.3047996 m: 1. Indian survey foot = 0.3047996 m

Feet and the entire imperial system are widespread throughout the US. In fact, it's only there. It's true that the US is regarded as being the only industrialized nation in the world who hasn't recognized the International System of Units, commonly referred to as the system of measurement in units of metric measurement. Two additional countries that employ this measurement system are Liberia located in Africa as well as Africa in Africa and Myanmar (also called Burma) in Southeast Asia. Canadians along with the British use a mixture of both systems: metric and imperial (e.g. the men's height is typically expressed in feet , though inches are also used).

Feets are not utilized widely in the non-English-speaking world. The most obvious example is an elevation measure within the international air travel industry.

Meter definition

Meter (British English: metre) is the basis length unit of several metrics, including those of the International System of Units (SI).

The definition of meter changed with the science of measuring evolved. The definition now can be defined as what is the course taken by light in a vacuum that is within 1/992,458 minutes.

What was its definition by the time it was first defined?

• The first tests of the definition of meter began in 1790. In 1790, 1790, the French National Assembly decided that the length of the new meter would be equal to the length of a pendulum , with an interval of one second for the half-period. Examine the precision of this figure making use of our calculator for pendulums. Enter 2 into the pendulum's time box and you'll then be able to calculate the pendulum length value. Indeed, it's really similar to the one meter (0.993621 1 m).

• In 1973 , the circumference Earth was used as a neutral reference point. The term "meter" was defined as one-ten millionth of the distance from the Equator to the north pole. North Pole: 1 meter is 1/10,000,000 of the meridional radius Earth that runs through the meridian between Earth and Paris
• Between 1799 and 1889, between 1799 and 1889 from 1799 to 1889. Brass, platinum, and the alloy of platinum with 10% iridium-based meter bars were made, with an element of the longitude of Earth's Meridian. In 1889, the 1st General Conference on Weights and Measures in 1889 defined the meter as the length that is the distance between two lines on a standard bar made of this alloy. This International Prototype Meter is still kept in the International Bureau of Weights and Measures in Sevres near Paris. This definition of meter was used until 1960 and the 11th General Conference on Weights and Measures.
• From 1960 until 1983, the meters were redesigned from 1960 to the year. It was renamed as 1,650,763.73 wavelengths derived from the orange-red radiation Krypton86 under certain conditions.
• 17th Conference defined"meter" as 1/299,792,458 of the distance light travels within a second. the definition for meters is still in force to.

The table below summarizes the chronology of a meter definition (by Cardarelli, 2003).

Standard	Date	Absolute error	Relative uncertainty

Imperial / US measurement system

The Imperial US measurement system as well as US measurement systems aren't the same, but for length measurements they're alike (they are different in volume measures, therefore e.g. the cup could contain an amount of floz that differs from both systems). The only countries that did not accept the metric system are that of US, Liberia and Myanmar.

six of the widely used US length units (also called imperial length units) were included in our length converter:

• the thousandth part of an inch (mil / to the thous),
• inches (in),
• feet (ft),
• feet and inches
• yards (yd),
• miles (mi).

Two more length units, however we've excluded them from this length converter on purpose: The term "furlong" refers to the fact that the furlong's conversion ratio isn't well-defined and the term league was the most commonly used measurement in Europe along with Latin America but is no ever an official measurement in any of the. You can however find them below, alongside the most widely used figures:

Unit	Comparative to the previous	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 measurements in metric units, also known as the International System of Units (SI) is an international decimal-based system for measuring and weights. It is widely used around the world (apart of the three countries mentioned in the previous paragraphs), it's easy to use, rational and practical. The four bases 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.

Alongside, 22 derivative units with their own names are available. We can split them into 5 categories:

1. Electromagnetism

• Volt is a measure of the electrical power
• ohm, a measurement of electrical resistance,
• tesla A measure of magnetic flux density
• weber is a sort of magnetic flux,

• Jourle, a unit of electrical, mechanical or thermodynamic energy
• Pascal is a measurement unit for pressure.

1. Radiofrequency

• sievert, a unit of absorption of the ionising radiation. You can estimate the radiation dose that you encountered while traveling to the airport with the radiation calculation calculator on flights.
• grey is an element of ionizing radiation
• "lux is a term used to describe luminescent flux
• lumen is a term that describes the intensity of light.

1. Circular arches as well as Spherical areas
