Units of length: millimetre and inch
A millimetre (mm) is a unit of length within the metric system of units, which in its current form is called the International System of Units (SI).
The base unit of length in SI is the metre. The prefix milli means "one-thousandth", so 1 millimetre equals 0.001 metre or 0.1 centimetre.
1 millimetre is approximately equal to 0.03937 inches.
An inch (in or ″) is a unit of length within the imperial system of units, a system of weights and measures traditionally used throughout the British Empire.
The imperial system was officially replaced by the metric system in almost all countries. Nevertheless, it is still widely used in the United Kingdom, Canada, and some other members of the Commonwealth, as well as in the United States.
1 inch equals exactly 25.4 millimetres or 2.54 centimetres.
