Meters to Millimeters (m to mm) Converter
1 meter (m) = 1,000 millimeters (mm). To convert meters to millimeters, multiply by 1,000: 100 m × 1,000 = 100,000 mm. Also searched as metre to millimeter, metres to millimeter, metres to millimetres.
Quick facts
- 1 m = 1,000 mm
- 1 mm = 0.001 m
- Formula: mm = m × 1,000
- Quick estimate: multiply by about 1000
How to convert meters to millimeters
- Take the value in meters.
- Multiply it by 1,000 (the number of millimeters in one meter).
- Round the result to the precision you need.
Worked example (a 100-metre sprint): 100 m × 1,000 = 100000 mm.
To convert millimeters back to meters, multiply by 0.001, or divide by 1,000.

What is a meter?
The SI base unit of length, originally defined from the Earth's meridian and now fixed by the speed of light. The standard unit of length across science, construction, and everyday use in most of the world.
What is a millimeter?
One thousandth of a meter, the SI base unit of length. Used for small, precise measurements in engineering, printing, and manufacturing tolerances.
Frequently asked questions
How many millimeters are in a meter?
There are 1,000 millimeters in 1 meter (1 m = 1000 mm).
