3 mtr in feet6/26/2023 Since you can multiply anything by 1 and still retain the original value, but in different units, set it up so that ft will cancel out leaving you with m.ġ ft 2 = 1 ft 2 * (1 m / 3.28084 ft) * (1 m / 3.28084 ft) = 0.0929030 m 2Īnd we now have our factor for conversion from ft 2 to m 2 since 1 * 0.0929030 = 0.0929030. ![]() Say you want to convert from ft 2 to m 2. To understand how to also convert the units follow this example. So, to convert directly from ft 2 to mm 2 you multiply by 92903.04. Or, you can find the single factor you need by dividing the A factor by the B factor.įor example, to convert from ft 2 to mm 2 you would multiply by 0.09290304 then divide by 0.000001. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into m 2 then divide by the factor for B to convert out of m 2. To convert from m 2 back into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.Ĥ.645152 m 2 / 0.09290304 = 50 ft 2 Multiply by the value in the right column in the table below.ĥ0 ft 2 * 0.09290304 = 4.645152 m 2 To simply convert from any unit into m 2, for example, from 50 ft 2, just Where S is our starting value, C is our conversion factor, and How to Convert Units of AreaĬonversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: 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.Convert units of area by entering the value to convert and the from and to units. 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 meter is defined as the distance traveled by light in 1/299 792 458 of a second. Meterĭefinition: A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). The international foot corresponds to human feet with shoe size 13 (UK), 14 (US male), 15.5 (US female), or 46 (EU). 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. 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. ![]() Definition: A foot (symbol: ft) is a unit of length in the imperial and US customary systems of measurement.
