Feet to Millimeters Converter
Convert feet (ft) to millimeters (mm)
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 based on the length of the human foot. Since the human foot commonly varies in length from about 9.5 inches to 11.5 inches, there were naturally regional variations in what constituted a foot. Due to these variations, it was eventually decided upon internationally that a foot should be defined as exactly 0.3048 meters, leading to the current definition.
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, room dimensions, ceiling heights, and shorter distances. Feet are also commonly used to measure altitude (aviation) as well as elevation (such as that of a mountain). The foot remains one of the most common units for everyday measurements in countries using the imperial system.
Millimeter
Definition: A millimeter (symbol: mm) is a unit of length in the International System of Units (SI). It is defined in terms of the meter, as 1/1000 of a meter, or the distance traveled by light in 1/299,792,458,000 of a second.
History/origin: The milli- prefix is one of many standard prefixes used in the metric system. It indicates one thousandth of the base unit, in this case the meter. The definition of the meter has changed over time, the current definition being based on the distance traveled by the speed of light in a given amount of time. The relationship between the meter and the millimeter is constant however. Prior to this definition, the meter was based on the length of a prototype meter bar. In 2019, the meter has been re-defined based on the changes made to the definition of a second.
Current use: Millimeters are often used in measuring small, precise dimensions in engineering, manufacturing, machining, and technical drawings. They are widely used in countries that have adopted the metric system. The millimeter is also commonly used to measure rainfall, snowfall, and other small measurements. In precision work, millimeters are preferred for their accuracy in measuring small objects and distances. They are standard units in construction, carpentry, metalworking, and scientific research.
