For all Length converters, choose units using the From/To dropdowns above.
A millimeter (mm) is a small unit of length in the metric system, equal to one-thousandth of a meter (1/1000 m or 0.001 m).
The word itself comes from the Latin "mille," meaning "thousand."
This is why the prefix "milli" in the metric system always means one-thousandth of a base unit—just like a milligram is one-thousandth of a gram.
The plural form is millimeters.
Understanding the relationship between millimeters and inches is crucial, particularly for projects that utilize both metric and imperial systems.
The official mm-to-inch conversion is a precise measurement used worldwide in engineering and manufacturing.
The millimeter is the standard unit for measuring small distances with precision.
You likely encounter millimeter measurements more often than you think in daily life, science, and technology.
The foot (ft) is a standard unit of length in the Imperial and U.S. customary systems of measurement.
The plural form is feet.
There are exactly 12 inches in a foot.
This fundamental conversion is the cornerstone of the Imperial and U.S. customary systems. It's a standard used everywhere, from measuring personal height to completing construction projects.
Additionally, it's helpful to know that 3 feet make one yard.
The origin of the "foot" as a unit of measurement is quite literal—it was historically based on the average length of a human foot.
Ancient civilizations, such as the Greeks, Romans, and Egyptians, often used body parts as a basis for measurement.
Because the actual length of a person's foot could vary, so did the measurement. This led to many inconsistencies until the foot was officially standardized.
Although most of the world uses the metric system, the foot is still an official unit of length in the United States.
It is also commonly used in countries such as the United Kingdom and Canada, particularly for measuring height, altitude, and property dimensions.
To establish a global standard, the international foot was defined in 1959 as being exactly 0.3048 meters.
This precise conversion is crucial for international science, trade, and engineering.
