Which abbreviation represents 1 millimeter?

Explanation:
Understanding metric prefixes helps you convert between units. Millimeter uses the prefix milli-, which means one thousandth of a unit. So a millimeter is 0.001 of a meter, and its abbreviation is mm. That tiny unit is much smaller than a meter (m), a centimeter (cm, which is 0.01 m), or a decimeter (dm, which is 0.1 m). Because millimeter represents 0.001 meters, mm is the correct abbreviation for 1 millimeter.
