Velocity
m/stomm/s
Convert metres per second (m/s) to millimetres per second (mm/s).
Factor1 m/s = 1000 mm/s
Converter
m/s
Accepts numbers or expressions, e.g. 150 + 14.7
Result
mm/s
Rendered to 6 significant figures.
Formula
Formula
mm/s = m/s × 1000
Multiply any value in metres per second by 1000 to obtain the value in millimetres per second.
Worked example
Convert 1 m/s to mm/s.
- 01Start with 1 m/s.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 mm/s.
Result1 m/s = 1000 mm/s

FAQ
What is the conversion factor from m/s to mm/s?
1 m/s equals 1000 mm/s. To convert, multiply the value in metres per second by 1000.
How do I convert 1 m/s to mm/s?
1 m/s = 1000 mm/s. For any value, multiply by 1000.
How do I convert mm/s back to m/s?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mm/s = 0.001 m/s.
When would I need to convert metre per second to millimetre per second?
Velocity conversions are needed for fluid flow analysis (line velocity targets, erosional limits), gas-stream calculations, and equipment specs that mix m/s, ft/s and engineering speed units.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
