# Convert feet to meters

Please provide values below to convert foot [ft] to meter [m], or *vice versa*.

### Foot

**Definition:** A foot (symbol: ft) is a unit of length in the imperial and US customary systems of measurement. A foot was defined as exactly 0.3048 meters in 1959. One foot contains 12 inches, and one yard is comprised of three feet.

**History/origin:** Prior to standardization of units of measurement, and the definition of the foot currently in use, the measurement of the foot was used in many different systems including the Greek, Roman, English, Chinese, and French systems, varying in length between each. The various lengths were due to parts of the human body historically being used as a basis for units of length (such as the cubit, hand, span, digit, and many others, sometimes referred to as anthropic units). This resulted in the measurement of a foot varying between 250 mm and 335 mm in the past compared to the current definition of 304.8 mm. While the United States is one of the few, if not only, countries in which the foot is still widely used, many countries used their own version of the foot prior to metrication, as evidenced by a fairly large list of obsolete feet measurements.

**Current use:** The foot is primarily used in the United States, Canada, and the United Kingdom for many everyday applications. In the US, feet and inches are commonly used to measure height, shorter distances, field length (sometimes in the form of yards), etc. Feet are also commonly used to measure altitude (aviation) as well as elevation (such as that of a mountain). The international foot corresponds to human feet with shoe size 13 (UK), 14 (US male), 15.5 (US female), or 46 (EU).

### Meter

**Definition:** A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). Currently, the meter is defined as the distance traveled by light in 1/299 792 458 of a second.

**History/origin:** Originally, in 1793, the meter was defined as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the International prototype metre was established as the length of a prototype meter bar (made of an alloy of 90% platinum and 10% iridium) measured at the melting point of ice. In 1960, the meter was again redefined, this time in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition of the meter was adopted in 1983.

**Current use:** Being the SI unit of length, the meter is used worldwide in many applications such as measuring distance, height, length, width, etc. The United States is one notable exception in that it largely uses US customary units such as yards, inches, feet, and miles instead of meters in everyday use.

**Possible future changes:** The definition of some SI base units may change in the near future. The International Committee for Weights and Measures (CIPM) has proposed re-definition of some of the SI base units in an attempt to further improve the system. Although the definitions of some units may change, the actual size of the units would remain the same; the change in definition will not have much (if any) effect on the daily use of these units.

The meter is one of the units that is being considered for another re-definition. Currently it is based on the length of the path travelled by light in a vacuum during a specific time interval, noted above. If changed, the new definition of the meter will be based on defining the fixed numerical value of the speed of light in vacuum as 299,799,458, expressed in units of m·s^{-1}, where the second is defined in terms of cesium frequency.

### How to Convert Foot to Meter

1 ft = 0.3048 m

1 m = 3.280839895 ft

**Example:** convert 15 ft to m:

15 ft = 15 × 0.3048 m = 4.572 m
