Millimeter (mm)
A millimeter is one thousandth of a meter — the metric workhorse for fine measurements and manufacturing tolerances.
Millimeters are used in engineering drawings, rainfall totals, and anywhere sub-centimeter precision matters.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 mm = 0.001 m
1 m = 1000 mm
To convert millimeter to meter, multiply by 0.001.
To convert meter to millimeter, multiply by 1000.
Example: convert 15 mm to m
15 × 0.001 = 0.015 m
About these units
Short background on the units used in this conversion.
Meter (m)
The meter is the SI base unit of length, defined by the distance light travels in a vacuum in a fixed fraction of a second.
Meters appear on road signs in most countries, in science and engineering, and anywhere the metric system is standard for measuring distance.
Frequently asked questions
