The international foot corresponds to human feet with shoe size 13 (UK), 14 (US male), 15.5 (US female), or 46 (EU).ġ5 m = 15 × 3.280839895 ft = 49. Feet are also commonly used to measure altitude (aviation) as well as elevation (such as that of a mountain). In the US, feet and inches are commonly used to measure height, shorter distances, field length (sometimes in the form of yards), etc. Easily convert feet per square minute to meters per square second, convert ft/m 2 to m/s 2. 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.Ĭurrent use: The foot is primarily used in the United States, Canada, and the United Kingdom for many everyday applications. 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. 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). 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. One foot contains 12 inches, and one yard is comprised of three feet. A foot was defined as exactly 0.3048 meters in 1959. Footĭefinition: A foot (symbol: ft) is a unit of length in the imperial and US customary systems of measurement. 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. The current definition of the meter is effectively the same as the definition that was adopted in 1983, with slight modifications due to the change in definition of the second.Ĭurrent use: Being the SI unit of length, the meter is used worldwide in many applications such as measuring distance, height, length, width, etc. 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. 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. History/origin: Originally, in 1793, the meter was defined as one ten-millionth of the distance from the equator to the North Pole. This definition was slightly modified in 2019 to reflect changes in the definition of the second. The accompanying acceleration unit is meters per second per second (m/s). This is the number of meters travelled in one second of time. The SI measurement of speed and velocity. The meter is defined as the distance traveled by light in 1/299 792 458 of a second. Feet per minute Feet per minute to Meters per second formula Meters per second. The m – ft converter above can help you with conversions for this unit of measurement.Definition: A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). It is used elsewhere, such as the UK, also as a measurement of height. Measurements in ftĪnother unit of length, feet are commonly used in the imperial system of the USA instead of the meter. Use our conversion from meters to feet tool to change measurements from meters to another unit. Meters can be subdivided into centimeters or millimeters, and are also multiplied to produce kilometers. This unit of length is used when measuring houses, height or slightly bigger everyday objects. As some examples, 2ft = 0.61m and 15ft = 4.57m. The manual calculation for this conversion would use the formula of ft / 3.2808 = m to give an accurate conversion and is the same conversion formula used by our online calculator m – ft. All of our converters are simply to use so try out the m to ft calculator above. If you are trying to calculate the other way, convert feet to meters. To convert meters into feet, enter the amount of meters you want to calculate into the box above and click ¨convert¨ for the new amount to appear in feet. Use any of our length converters for unit conversions, including the meter to feet converter above for accurate conversions. These two units of length are common in our everyday language, however the meter is used less in the United States and in replacement the foot is used.
