We've made a decision to round a few of the variables used in conversion so that they can be included in this tableau. Therefore, certain numbers aren't precise, but they still have some degree of precision.

Length conversion chart

When you're trying to determine how to quickly convert between units in one system, you should look at these two simple length conversion charts:

1. The method of measuring metrics.

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

Inch definition

The inch (abbreviate in the sense of or ") is a measure of length within the Imperial or US systems of metric measurement. The term originates from a variety of definitions, including the size 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 cases, the same word. From the 14th century onwards the definition of an inch was given by King George V of England by a definition of three barley grains, dry and round, laid between the ends, lengthwise. The definition of an inch changed through the ages but during the 1950's, an international standard was accepted, and, since then the inch is exactly 2.54 centimeters.

1 in = 2.54 cm

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

On a daily basis inches are widely used throughout the US, UK, Canada and many other nations that were previously part of the British Empire. Along with length, width and height are measured in the same way, as are various sizes measured in units derived from inches (e.g. shoe size).

What is measured in inches? Not just in the US but all over the world?

• screen sizes of monitors, smartphones TVs, and monitors (specifically dimensions of diagonals in rectangle screens)
• resolution for the display PPI (pixels per inch)
• dimensions of tires (e.g. car or bike wheels) e.g. car or bike wheels
• different equipment and sizes
• Certain sports equipments employ the inch value. e.g. when shooting archery.
• in the sciences, e.g. Acoustics are microphones and the dimensions of loudspeakers

One International inch is the same as:

• 10,000 tenths
• 1000 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 the total of 0.333 palms
• 1/4 or 0.25 hands
• 1/12, or 0.08333 feet
• 1/36 or 0.02777 yards

Feet definition

Foot (abbreviate as ft or ') is one of the length units that are used within the Imperial or US standard system of measurement. It's a measurement built on the human body as the name implies. The measurement has been standardized in the 50s and since then it's equal 0.3048 meters precisely:

1 ft = 0.3048 m = 304.8 mm

The use of feet has been utilized since the beginning of time throughout various civilizations however, the length of the feet varied among these different cultures. The foot was commonly used, e.g. in:

• Ancient Rome: 1 foot equals 11.6 inches (295.7 millimeters). This was a standard size foot, but in some provinces it could be as wide 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 equals 12 inches (304.8 millimeters)

The non-official imperial standard for public measurement, Greenwich

The measurement of feet is used in England In England the measurement of the foot also changed through the years beginning with Roman standards, and later Belgic Celts foot of 13.2 inches or Welsh foot was introduced and eventually discarded. The feet definition varied between regions, city to city, and finally the kings changed the measurement in accordance with their wishes - e.g., Henry I was believed to have issued a new standard based upon his arm. Following that, Edward II of England introduced some form of standardization that introduced the statute foot that was 10/11 the length of the prior foot. The finalization of the length of the foot was achieved much later in the year 1959, after the International yard-and-pound treaty came into force. 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 measured as well. This is equivalent to:

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

Within the US two types of feet are employed on regular intervals, that is the international foot as well as the survey foot:

1. International foot is also known as the standard foot, it was first standardized during the 50s. Widely used in range of fields, it's the equivalent of 0.3048 m: 1 international foot 0.3048 millimeters and we've used the symbol to illustrate it is a significant number. The international measure is equivalent to one human foot having the size of 13 (UK) and the size of 14 (US male ).
2. Survey foot The US survey foot is nearly identical in size to the foot of the globe. However, the word nearly is the most important . The survey foot definition is exactly 1200/3937 metres 1 US survey foot = 1200/3937 m 0,30480060960121920243840487680975... m As you will see, it appears like a really tiny difference but something is different when you get to seven decimals! The difference is just 0,609 mm 609 nanometers, when comparing one type of foot with the other. Why should we be concerned? important because the difference isn't significant when measuring objects that are relatively small, however , the difference is significant when we start measuring thousands of feet using mapping, and using state-plane coordinate systems (SPCS). In addition, the laws on the survey foot varies across the 50 states.
   • 24 states have passed legislation that states that surveying measures should be based upon the US feet of the survey. US feet of the survey
   • 8 states have voted to make an announcement in line with the global foot
   • 18 states haven't defined the conversion rates for metric units. Don't be concerned too much If you're in necessity of the change in your routine conveyances or surveying of land. The variation is negligible for distances of a short distance (< 1 mile) and it doesn't matter what definition you decide to go with.
   Another measurement of the foot, namely the Indian survey foot . It's described as precisely 0.3047996 M: 1. Indian survey foot equals 0.3047996 m

Feet as well as the entire imperial system is utilized widely across the US. And almost only there. The US is regarded as being the one industrialized nation in the world which hasn't been able to accept its International System of Units, commonly referred to as the system of measurement using the metric unit. Two additional countries that employ this system of measurement include Liberia in Africa within Africa in Africa and Myanmar (also named Burma) in Southeast Asia. Canadians along with the British utilize a combination of both systems, imperial and metric (e.g. the men's height is typically measured in feet , however inches are also utilized).

Feets aren't used widely in non-English-speaking countries. The most obvious example is that of the elevation measurement within the international air travel industry.

Meter definition

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

The definition of meter changed when the methods used to measure scientifically changed. The definition now refers to which is direction traveled by light in a vacuum, which is 1/99,792,458 second.

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

• The initial tests for the definition of meter began in 1790. In 1790 it was decided by the French National Assembly decided that the length of a 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 number using our pendulum calculator. Enter 2 into the pendulum period box, and you'll then be able to calculate the pendulum length value. Actually, it's close to the one meter (0.993621 millimeters).

• In 1973 , the circumference Earth was chosen as a neutral standard. The term "meter" was defined as one-ten millionth of the distance from the Equator to the north pole. North Pole: 1 meter is one-tenth of the quarter meridional radius of the Earth that extends between the Earth and Paris
• Between 1799 and 1889 from 1799 to 1889. Brass, platinum, and the platinum alloy with 10% iridium meter bar were developed, on basis for a bar that was the length of Earth's meridian. It was the 1st General Conference on Weights and Measures in 1889 established the Meter as the distance which lies between two lines on a standard bar made of this kind of alloy. This International Prototype Meter is still maintained within the International Bureau of Weights and Measures located in Sevres near Paris. The meter definition was used until 1960 and the 11th General Conference on Weights and Measures.
• From 1960 until 1983 the meters were redefined during the decade of 1960. The name was changed to 1,650,763.73 wavelengths of the orange-red radiation Krypton86 under certain conditions.
• 17th Conference defined"meter" to mean 1/299,792,458 of the distance light travels in a second. Its definition of meters is still in force to.

The table below summarizes the time-line of a meter's definition (by Cardarelli, 2003).

Imperial / US measurement system

Imperial The US measurement system as along with US measurement systems aren't identical in terms of length measurement, but they're similar (they differ in terms of volume, which means e.g. the cup could contain an amount of floz that differs from both systems). The only countries not to accept measures in metric included the US, Liberia and Myanmar.

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

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

Two additional length units, but we've removed them from this length converter on purpose: The term "furlong" refers to the fact that the length of a furlong's conversion ratio is not well-defined and the term league used to be the most used measurement across Europe and Latin America but is no any longer an official measurement for any one of them. You can however find them below, as well as the most commonly used values:

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 called"the International System of Units (SI) has an international decimal-based system for measurement and weights. It is widely used across the globe (apart of the three countries mentioned in the preceding paragraphs), it's easy to use, rational and practical. The four bases units of the metric measure system is:

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