We've decided that we'll round a couple of the variables for conversion to ensure they fit into this table. So, some numbers aren't exactly accurate however they do 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 basic 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 measuring system. US measure system

For instance:

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

In addition, we've decided to compile an index of the most popular length conversions. The most common ones that you'll want to look for are:

1. meters to feet/ feet-to-meters

If you're trying to figure out how many feet are in a meter, here you're:

• 1 Meter 3.281 feet which equals 3 feet and 3 3/4 inches
• 1 foot equals 0.3048 Meter

1. cm to inches/ inches to cm

Find out the centimeters that make up an inch.

• One centimeter 0.3937 inches
• 1 inch equals 2.54 centimeters

1. feet-to-inchesin inches

To convert between feet and inches you can use:

• 1 foot equals 12 inches
• 1 in 0.08333 feet 1/12 of one foot

1. yards to feet/ yards to feet

How many yards can be accommodated in your 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 as in or ") is a measurement of length in the Imperial or the US standard system of metric measurement. The word comes from several definitions - the size of the human thumb. In certain different languages e.g. Norwegian, Afrikaans, Italian or French the word "inch" originates from the word thumb in certain cases, it's the same concept. From the 14th century onwards An inch was defined by King George V of England by a definition of three barley grains, dry and round, laid out between the ends and lengthwise. The definition of an inch changed through the centuries, but in the 1950's, a standard for international use was adopted, and, since then, an inch is exactly 2.54 centimeters.

1 in = 2.54 cm

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

On a daily basis inches are widely used across countries like the US, UK, Canada and many other countries which were once members of the British Empire. Along with length, width, and width can be measured in the same way, as are various sizes measured by units made up of inches (e.g. sizes of shoes).

What is measured in inches? It's not only across the US however, but around the globe?

• screen sizes of monitors, smartphones TVs, monitors (specifically dimensions of diagonals on rectangular screens)
• resolution on the screen PPI (pixels per inch)
• dimensions of tires - e.g. bicycle or car wheels,
• different tools and pipes of various sizes
• certain sports equipments use the value of inches. e.g. used in archery.
• in 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 Tenths
• 1,000 thou/mil
• 100 points or tears
• 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 to 0.25 hands
• 1/12 (1/12) or 0.08333 feet
• 1/36 or 0.02777 yards

Feet definition

Foot (abbreviate in the form of "ft," or ') is one unit of length used in the Imperial or US standard system of measuring. It's a measurement based on the human body as the name implies. The measurement has been standardized in the 50s and since then, it's equal to 0.3048 meters precisely:

1 ft = 0.3048 m = 304.8 mm

The use of feet been utilized since ancient times across various civilizations, however, the length of the foot varied from one culture to the next. The foot was utilized, e.g. in:

• Ancient Rome: 1 foot = 11.6 inches (295.7 mm). This was a standard-sized foot, however in some provinces, it may be as large than 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 in feet (304.8 millimeters)

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

The measurement of feet is used in England The measurement of feet in England 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 then gone. The feet definition varied in different regions, and city to city, and finally the kings altered the measure as per their own preferences - e.g., Henry I was said to have ordered the creation of a new standard, based on his arm. Following that, Edward II of England introduced some kind of standardization and introduced the statute foot which was 10/11 of the earlier foot. The finalization of the length of the foot was reached much later, in 1959, after it was the year that the International yard-and-pound convention came into force. Since then, the length of a yard in the United States and countries in the British Commonwealth is equal to exactly 0.9144 meters. The first time yard measurement was established, the foot could be calculated in the same way. This is similar to:

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

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

1. International footAlso called the standard foot and was first standardized during the 50s. It is widely used in a range of different applications, it's actually the equivalent to 0.3048 millimeters: One international foot 0.3048 millimeters and we've used the symbol to indicate that it is precisely this number. The international measure is the equivalent of the human foot, which has the dimensions of 13 (UK) as well as fourteen (US male).
2. Survey foot It is the US survey foot is almost identical in measure to the bottom of the earth. However, the word About is the key . The definition of survey feet is exactly 1200/3937 meters. 1 US survey foot = 1200/3937 m 0,30480060960121920243840487680975... m As you will see, this appears like a tiny difference - something changes when you reach the seventh decimal! The difference is just 0,609 mm 609 nanometers when you compare one kind of foot to the other. Why is this important? It is important because the distinction is minimal when measuring relatively small objects, however , the difference is significant when we start measuring hundreds of thousands feet, like when mapping or using the state plane coordinate system (SPCS). In addition, the laws governing the survey foot differs among all 50 states.
   • 24 states have adopted law that stipulates that surveying measures must be based on US Survey foot. US feet of the survey
   • 8 states have decided to make the announcement in line with the world foot
   • 18 states are yet to specify the percentage of the conversion for metric units. However, don't fret about it too much if you're in need of the conversion for your normal conveyances, or when you're surveying of land, the difference is really negligible for shorter distances (less than one mile) and it doesn't matter what definition you settle on.
   Another measurement for 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 utilized widely throughout the US. The only exception is in the US. The US has the distinction of being the only industrialized nation in the world that hasn't yet recognized its International System of Units, which is also known as the system of measurement in units of measurement in metric units. Two other countries that use this measurement system include Liberia inside Africa within Africa as well as Myanmar (also called Burma) in Southeast Asia. Canadians along with the British use a mixture of both systems, imperial and metric (e.g. the men's height is typically expressed in feet , however inches are also utilized).

Feet aren't widely used in the non-English-speaking world. The most obvious example could be that of the measuring of elevation in the air travel industry.

Meter definition

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

The definition of meter changed when the scientific methods of measuring developed. The definition is that of the course traveled by light in a vacuum that is within 1/992,458 seconds.

What was its definition through the years?

• The first trials of the definition of meter began in 1790. In 1790 the French National Assembly decided that the length of a new meter should be the same as its length the pendulum and an average half-period of 1 second. Find out the exactness of this figure making use of our calculator for pendulums. Type 2 in the pendulum's period box and you'll be able determine the length of the pendulum. In reality, it's very close to the one-meter mark (0.993621 millimeters).

• In 1973, the circumference Earth was chosen as a neutral reference point. The meter was defined as one-ten-millionth of the distance between the equator up to the north pole. North Pole: 1 meter is one-tenth of the quarter meridional radius Earth that extends through the meridian connecting two points: the Earth and Paris
• Between 1799 and 1889, between 1799 and 1889, brass platinum and the mixture of platinum and 10% iridium meters were developed, on an example of a base that was the length of the meridian on Earth. In the 1st General Conference on Weights and Measures in 1889 defined the meter as the length which is measured between two lines within a typical bar made from this kind of alloy. This International Prototype Meter is still kept within the International Bureau of Weights and Measures in Sevres close to Paris. That meter definition was used up to 1960, and then in the 11th General Conference on Weights and Measures.
• From 1960 until 1983, the meters were changed in the year 1960. The name was changed to 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 within a second. Its definition of meter is still in force to the present.

The table below summarizes the history of the definition of a meter (by Cardarelli in 2003).

Standard	Date	Absolute error	Relative uncertainty
One-tenth of a million in the Quadrant which runs along the Meridian	1795	500-100 mm	10 -4
The first prototype for the platinum bar standard	1799	50-10 mm	10 -5

Imperial (US) measurement system. US measurement system

In the US, the Imperial US measurement system as well the US measurement systems aren't the same, but for length measurements they're alike (they are different in volume measures, so e.g. the cup could have certain amount of floz, which is different from the two systems). The only countries that did not accept metrics were the US, Liberia and Myanmar.

A total of six of the widely used US length units (also known as imperial length units) were included in our length converter:

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

There are two additional length units, however we have excluded these from the 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 was previously the most popular measurement in Europe along with Latin America but is no anymore an official unit across any region. However, you can find them below, alongside the most popular values:

Unit	When compared to the preceding	Feet	Millimeters	Meters
Thous (th)		1/12000	0.0254	0.0000254

Metric measurement system

The measurement system metric, also called"the International System of Units (SI) uses an international decimal system that is used for weights and measurements. It is widely used across the globe (apart one of the countries listed in the earlier paragraphs), it's easy to understand, rational, and practical. The four fundamental units of the measuring system in metric are:

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

Additionally, 22 derivative units with their own names are also available. They can be divided into 5 categories:
