Speed converter

meter per second to millimeter per second

Convert meter per second (m/s) to millimeter per second (mm/s). Use an editable speed converter, conversion formula, and reference table.

1,000

1 m/s = 1,000 mm/s

Calculated in your browser

Conversion formula

mm/s = m/s × 1,000

One meter per second equals 1,000 millimeter per second. Multiply your value in meter per second by this factor to get millimeter per second. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 meter per second:
5 × 1,000 = 5,000 mm/s

About these measurements

Speed is distance traveled per unit of time.

The base reference used here is the meter per second. One meter per second is 1 base units; one millimeter per second is 0.001 base units.

Important distinctions

Mach is excluded because the speed of sound depends on medium and temperature.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert m/s to mm/s?

Multiply the quantity in m/s by 1,000. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the millimeter per second to meter per second converter.
