We've decided to round off a some of the conversion variables so that they can fit into this table. Thus, certain values aren't exact but they have some level of accuracy.

Length conversion chart

You're looking for a way to quickly change between units within one system, look into these two simple length charts:

1. The measurement system metrics.

Let us give an example

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

1. Imperial US measurement system. US measure system

For example:

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

Additionally, we've decided to compile a list with the most requested length conversions. The most common ones you'll be looking for are:

1. meters to feet/ feet-to-meters

Are you trying to figure out the number of feet in the meter, here you're:

• 1 Meter 3.281 feet that is equivalent to 3 feet and 3 3/4 inches
• 1 foot equals 0.3048 Meter

1. cm to inches/ inch to centimeter

Find out the centimeters that make up an inch.

• One centimeter 0.3937 inches
• 1 inch equals 2.54 centimeters

1. feet to inchesand inches to feet

To convert between feet and inches you can use:

• 1 foot = 12 inches
• 1 . 0.08333 feet 1/12 of a foot

1. yards to feet/ yards to feet

How many feet of space can be squeezed into the yard? Three!

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

1. feet to miles/ miles to miles

Have you ever thought about how many feet you can count in a mile?

• 1 foot 0.00018939 mile
• 1 yard = 5280 feet

Inch definition

The inch (abbreviate meaning "or ") is an measure of length within the Imperial or the US the metric system. The word comes from several definitions - the width of the thumb. In some languages e.g. Norwegian, Afrikaans, Italian or French the word "inch" originates from the word thumb or in certain cases, it's the same idea. From the 14th century to the present, an inch was defined as by the King of England by a definition of three barley grains which were dry and round, laid out between the ends in a lengthwise. The definition of the inch varied throughout the ages , but by the 1950's, a standard for international use was adopted and, since then, the inch is exactly 2.54 centimeters.

1 in = 2.54 cm

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

On a regular basis, inches are widely used throughout many countries, including the US, UK, Canada and a host of other countries that were previously as part of the British Empire. Along with length, width and width are measured in several sizes. They are also determined by units made up of inches (e.g. shoes size).

What is measured in inches? It's not just for the US however, but all over the world?

• screen sizes of monitors, smartphones, TVs, (specifically dimensions of the diagonals in rectangular screens)
• resolution for the display PPI (pixels per inch)
• size of tires - e.g. bicycle or car wheels,
• different tools and pipes of various sizes
• Certain sports equipments utilize the inch value. e.g. in archery.
• in the field of science, e.g. Acoustics in science, for instance. Acoustics microphones, and the dimensions of loudspeakers

The term "International inch" refers to: International inch is the same as:

• 10,000 10ths of a tenth
• 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 or 0.333 palms
• 1/4 or 0.25 hands
• 1/12 (1/12) or 0.08333 feet
• 1/36 or 0.02777 yards

Feet definition

The word foot (abbreviate to "ft," or ') can be described as one of the measurement units utilized within the Imperial or US standard system of measurement. It's a measurement that is based on the human body as the name suggests. The measurement has been 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 been used since the beginning of time in various cultures, however, the length of a foot varied among these different cultures. The foot was used, e.g. in:

• Ancient Rome: 1 foot = 11.6 inches (295.7 mm). This was a standard size foot however in some provinces, it may be as large in size as 13.2 inches (334 mm)
• 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 of 12 inches (304.8 millimeters)

The imperial public measure that is not official. standards, Greenwich

The measurement of the foot is used in England In England the measurement for feet was also altered over the years starting with Roman standards, and then Belgic Celts foot of 13.2 inches or Welsh foot was introduced and it was removed. The feet definition varied between regions, and city to city, then the kings modified the measure according to their preferences. e.g., Henry I was believed to have ordered the creation of a new standard, based on his arm. Following that, Edward II of England introduced some kind of standardization. He introduced the statute foot that was 10/11 of the earlier foot. The finalization of the foot's length was made much later in the year 1959 following the International yard-and-pound convention was signed. Since then, yard length in the United States and countries in the British Commonwealth is equal to exactly 0.9144 meters. At the time that yard length was initially defined and the foot was also a factor, it could be determined as well. This is equivalent to:

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

In the US two types of feet are utilized on a regular basis that is the international foot, and the survey foot:

1. International footAlso known as the standard foot and was first standardized during the 50s. It is widely used in a range of fields, it's the equivalent to 0.3048 meters: 1 . International foot 0.3048 millimeters and we've utilized the symbol to convey the significance of exactly this amount. The international measure is the equivalent of one human foot having 13 inches of size (UK) and the size of 14 (US male).
2. Survey foot It is the US survey foot is nearly identical in size to the bottom of the earth. But the word nearly is the main . The survey foot definition is exactly 1200/3937 meters 1 US survey foot = 1200/3937 m 0,30480060960121920243840487680975... m As you can see, it seems like a small amount of difference , but it's actually a big change at the 7th decimal! It's less than 0,609 millimeters 609 nanometers, when you compare the one foot type to the other. Why should we care? Important because the difference isn't significant when measuring objects that are relatively small, however , the difference is significant when we start measuring hundreds of thousands of feet like when mapping or using an state-plane coordinate system (SPCS). Further, the legislation regarding the survey foot differs among all 50 states.
   • 24 states have passed law that stipulates that surveying measures must be based upon US surveys foot. US Survey feet are the foot that is used for surveying.
   • Eight states have voted to make the announcement in accordance with the global foot
   • 18 states are yet to specify the percentage of the conversion for the metric unit. However, don't fret all that much if you're need of the conversion for your everyday conveyances or surveys of land. The difference is not that significant for short distances (< 1 mile) and it doesn't matter which definition you choose to use.
   There's another measurement of the foot: 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 are utilized widely throughout the US. The only exception is in the US. It's true that the US has the distinction of being the one industrialized nation in the world that hasn't yet adopted the International System of Units, which is also known as the system of measurement in units of measurement in metric units. Two other countries using the system of measurement include Liberia in Africa as well as Africa and Myanmar (also known as Burma) which is located in Southeast Asia. Canadians and the British make use of a mix of both systems: metric and imperial (e.g. the men's height is typically expressed in feet , however inches can also be used).

Feet are not used widely in the non-English-speaking world. The most obvious illustration could be that of the measuring of elevation in the international air travel industry.

Meter definition

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

The definition of meter was changed in the course of how scientific methods of measuring changed. The definition now is what is the route traveled by light in a vacuum within 1/99,792,458 seconds.

How was it defined through the years?

• The first trials of the meter definition started in 1790. In 1790 1790, the French National Assembly decided that the length of the new meter should be equal to its length a pendulum , with one second of a half-period. You can verify the accuracy of this number the pendulum calculator. Type 2 in the pendulum's duration box, and you'll have the ability to determine the length of the pendulum. Indeed, it's really close to one meter (0.993621 meters).

• In 1973, the circumference of Earth was chosen as a neutral reference point. The term "meter" was used to mean one-tenth of the distance that runs from the equator until the north pole. North Pole: 1 meter is 1/10,000,000 of the quarter meridional radius of the Earth that is located along the meridian between both the Earth and Paris
• 1799 to 1889 in the period between 1799 between 1889 and 1799, brass, platinum and the alloy made of platinum with 10% iridium meters were invented, to form an element that could be used as a base for the length of the Earth's meridian. This was in the 1st General Conference on Weights and Measures in 1889 established the meter as the distance that is between the two lines of a standard bar made from this kind of alloy. The International Prototype Meter is kept inside the International Bureau of Weights and Measures located in Sevres just outside of Paris. The definition of meter was used from 1960 until the 11th General Conference on Weights and Measures.
• Between 1960 and 1983, the meters were redesigned during the decade of 1960. It was renamed as 1,650,763.73 wavelengths from the red-orange radiation Krypton86 under certain conditions.
• 17th Conference defined"meter" to be 1/299,792,458 in the sense of how much light travels per second. Its definition of the meter has been in effect up to the present.

The table below provides the timeline of the meter definition (by Cardarelli 2003).

Imperial (US) measurement system. US measurement system

It is known as Imperial. US measurement system as well the US measurement systems aren't the same however, in terms of length measurements they're similar (they differ in volume measures, so e.g. the cup could contain quantity of floz that is different from the two measurement systems). The only countries that didn't accept the metric system included three countries: the US, Liberia and Myanmar.

Six of the most widely employed US length units (also known as imperial length units) were included in our length converter:

• 1 millimeter (mil / one thousandth of an inch (mil/thou),
• inches (in),
• feet (ft),
• feet and inches
• yards (yd),
• miles (mi).

There are two more length units, but we've removed them from this length converter on purpose: The term "furlong" refers to the fact that a "furlong"'s conversion ratio is not widely defined and the term league used to be the most popular measurement used in Europe in Europe and Latin America but is no anymore an official unit across any region. However, you can find them below, as well as the most widely used values:

Unit	Comparatively to the previous	Feet	Millimeters	Meters
Thous (th)		1/12000	0.0254	0.0000254
inch (in)	1000 thou	1/12	25.4	0.0254

Metric measurement system

The measurement system metric commonly referred to as"the International System of Units (SI) includes an international decimal system that is used for measurements and weights. It is widely used throughout the globe (apart of the three countries discussed in the earlier paragraphs), it's easy to use, rational and practical. The four base units of the measure system of metric measurements are:

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

Apart from that, 22 derivative units that have their own names exist. They can be divided into five categories:
