We've decided to round off a some of the conversion variables so that they can fit into this table. Thus, certain values may not be exact, but they still have some degree of precision.

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 system of measuring metrics.

For example:

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

1. Imperial US measurement system. US measure system

For instance:

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

In addition, we've taken the decision to compile a list of the most commonly requested length conversions. The most frequently requested ones that you'll want to look for are:

1. meters to feet / feet-to-meters

When you're trying determine how many feet are contained in a meter you're:

• 1 Meter 3.281 feet which is equal to 3'3 inches
• 1 foot equals 0.3048 Meter

1. cm to inches / inches to inches

Find out the amount of centimeters in an inch.

• One centimeter 0.3937 inches
• 1 inch equals 2.54 centimeters

1. feet and inchesin inches

To convert between inches and feet you can use:

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

1. feet to yardsor yards to feet

How many feet could 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 wondered how many feet there are in one mile?

• 1 foot 0.00018939 mile
• 1 yard = 5280 feet

Inch definition

The inch (abbreviate meaning "or ") is a measure of length used in the Imperial or the US metrics system. The term comes from a few definitions - the width of the thumb. In some language e.g. Norwegian, Afrikaans, Italian or French the word "inch" originates from the word"thumb" or in certain cases, it's the same idea. Since the 14th century onwards, an inch was defined in the reign of King Edward I. England to be three grain of barley which were dry and round, laid out between the ends of the lengthwise. The definition of the inch varied throughout the ages , but by the 1950's an international standard was adopted, and, since then, an inch is equivalent to 2.54 centimeters.

1 in = 2.54 cm

One inch also corresponds one-third of one 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 as well as other countries which were once an integral part of the British Empire. Along with width, length and height can be measured in different sizes, and also measured in units that are derived from inches (e.g. the size of a shoe).

What can be measured in inches, not only in the US however, but around the globe?

• screen dimensions of smartphones, monitors, TVs, (specifically dimensions of the diagonals on rectangular screens)
• Resolution of screen PPI (pixels per inch)
• dimensions of tires size of tires e.g. car or bike wheels,
• different tools and pipes of various sizes
• certain sports equipments use the inch value. e.g. within archery.
• in the field of science, e.g. Acoustics in science, for instance. Acoustics microphones as well as the diameters of loudspeakers

One International inch is the equivalent to:

• 10,000 tenths
• 1,000 thou/mil
• 100 points or grries
• 72 PostScript points
• 6 computer picas
• 3 barleycorns
• 2.54 centimeters exactly
• 0.999998 US Survey inches
• 1/3 of 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 with "ft" or ") is one unit of length utilized as part of the Imperial or US standard system of measuring. It's a measurement that is based on the body of a human as the name implies. The measurement was standardized in the 50s , and since then it's equal to 0.3048 meters exactly:

1 ft = 0.3048 m = 304.8 mm

The use of feet been in use since ancient times throughout various cultures however the length of the foot varied between these cultures. The foot was used in various ways, e.g. in:

• Ancient Rome: 1 foot = 11.6 inches (295.7 mm). This was a standard foot, but in some provinces it could be as long than 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 It is the equivalent of twelve inches (304.8 millimeters)

The official imperial public measurement standards, Greenwich

The foot measurement is used in England It was in England the foot measurement also changed through the years and was first introduced in Roman standards and was later changed to Belgic Celts foot of 13.2 inches or Welsh foot was introduced, but it was removed. The definition of feet varied in different regions, city to city, then the kings altered the measure in accordance with their wishes - 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, introducing the statute foot that was 10/11 shorter than the previous foot. The end of the foot's length was reached much later, in the year 1959 following it was the year that 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. In the beginning, when yard first established in the first place, feet could be determined as well. This is similar to:

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

In the US two kinds of foot are employed on a regular basis: the international foot, as well as the survey foot.

1. International footAlso known as the standard foot, it was first standardized in the 50s. Widely used in a variety of settings, it's the equivalent of 0.3048 m: 1 international foot 0.3048 millimeters and we've utilized the symbol to convey the significance of exactly this quantity. The measure used internationally is equivalent to 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 practically identical to the foot of the world. However, the word Nearly is the primary . The definition of survey feet is exactly 1200/3937 metres 1 US survey foot = 1200/3937 m 0,30480060960121920243840487680975... m As you can see, it appears like a tiny variation - however, something happens as you approach the seventh decimal! The difference is tiny 0,609 mm, 609 nanometers, when comparing the one foot type to the other. Why is this important? It is important because the distinction is minimal when we are taking measurements of relatively small objects however it increases significantly when we begin to measure hundreds of thousands of feet for example, when mapping or using SPCS, the State Plane Coordinate System (SPCS). Furthermore, the legislation on the foot survey differs across the 50 states.
   • 24 states have adopted legislation that states that surveying measures must be based upon US survey foot. US surveys are based on feet.
   • 8 states have voted to make the announcement in line with the global foot
   • 18 states do not have a specific conversion rate for metric units. But do not fret too much If you're in need of the conversion for your normal conveyances, or when you're surveying of your land, the difference is really negligible in short distances (less than 1 mile) and it doesn't matter what definition you settle on.
   There's 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 is utilized widely throughout the US. In fact, it's almost exclusively used in the United States. It's true that the US has the distinction of being the only industrialized nation in the world who hasn't been able to accept its International System of Units, which is also known as the system of measurement in units called metric. Two other countries using this method of measuring are Liberia within Africa within Africa in Africa and Myanmar (also known as Burma) within Southeast Asia. Canadians as well as the British utilize a combination of both systems: metric and imperial (e.g. the men's height will typically be measured in feet, however inches are also used).

Feet aren't used extensively in the non-English-speaking world. One of the most obvious examples would be to measure elevation in the international air travel industry.

Meter definition

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

The definition of meter has changed as the methods of scientific measuring changed. The definition is which is course of light that is traveled in a vacuum in less than 1/99,792,458 seconds.

How was it defined in the past?

• The initial tests of the definition of meters began in 1790. In 1790, 1790, the French National Assembly decided that the length of a new meter would be exactly what is the size of the pendulum and an average half-period of 1 second. Examine the accuracy of this figure the pendulum calculator. Enter 2 in the pendulum's period box and you'll be able calculate the length of the pendulum. It's actually near to the 1 meter (0.993621 m).

• In 1973, the diameter of Earth was chosen as a neutral standard. The meter was defined as one-tenth of the distance that runs from the equator to north pole. North Pole: 1 meter is 1/10,000,000 of the quarter meridional circle of Earth that is located across the meridian that connects two points: the Earth and Paris
• Between 1799 and 1889, and 1889, brass, platinum and the alloy made of platinum and 10% iridium-based meter bars were developed, on an example of a base that was the length of the meridian of Earth. The 1st General Conference on Weights and Measures in 1889 established the meter as the length which is measured between two lines on a standard bar made of this type of alloy. The International Prototype Meter is kept inside the International Bureau of Weights and Measures located in Sevres close to Paris. That meter definition was used in the 1960s and during the 11th General Conference on Weights and Measures.
• Between 1960 and 1983, the meters were revised from 1960 to the year. It was renamed as 1,650,763.73 wavelengths derived from the red-orange radiation Krypton86 under certain conditions.
• 17th Conference defined"meter" as 1/299,792,458 of how far light travels in a second. This definition of the meters remains in effect up to.

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

Standard	Date	Absolute error	Relative uncertainty

Imperial / US measurement system

Imperial the US measurement system as well as US measurement systems aren't the same however for length measurements they're the same (they are different in volume measurements, meaning e.g. the cup might contain an amount of floz that differs from both measurement systems). The only nations that didn't accept metric units were those of the US, Liberia and Myanmar.

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

• One thousandths of an inch (mil / thou),
• Inches (in),
• feet (ft),
• feet and inches
• yards (yd),
• miles (mi).

There are two more length units, however we've excluded these from the length converter on purpose: The term "furlong" refers to the fact that a "furlong"'s conversion ratio is not broadly defined, and the term league used to be the most popular measurement used in Europe as well as Latin America but is no any longer an official measurement within any. They are however available below, along with the most frequently used values:

Unit	In comparison 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
yard (yd)	3 feet	3	914.4	0.9144
chain (ch)	22 yards	66	20116.8	20.1168
furlong (fur)	10 chains	660	201168	201.168
mile (mi)	8 furlongs	5280	1609344	1609.344

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's widely used around the world (apart from the 3 countries listed in the earlier paragraphs) It is simple to use, practical and practical. The four fundamental units of the measure system of metric measurements are:

• meters ( m) for length
• kg ( kg) for mass (check out this conversion of weight),
