A millimeter (mm) is a unit of length in the International System of Units (SI) equal to one thousandth of a meter (0.001 meters) or one tenth of a centimeter (0.1 cm)
. It is used to measure very small lengths or thicknesses precisely. In terms of inches, one millimeter is exactly 0.03937 inches, since one inch equals 25.4 millimeters
. For example, 1 mm is approximately 1/32 of an inch
. To summarize:
- 1 mm = 0.001 meters
- 1 mm = 0.1 centimeters
- 1 mm ≈ 0.03937 inches (about 1/32 inch)
- 1000 mm = 1 meter
- 10 mm = 1 centimeter
This makes the millimeter a very small unit ideal for measuring tiny distances or dimensions such as thicknesses, small objects, or precise lengths
