Velocity

cm/stomm/s

Convert centimetres per second (cm/s) to millimetres per second (mm/s).

Factor1 cm/s = 10 mm/s

Converter

cm/s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
10mm/s

Rendered to 6 significant figures.

Formula

Formula
mm/s = cm/s × 10

Multiply any value in centimetres per second by 10 to obtain the value in millimetres per second.

Worked example

Convert 1 cm/s to mm/s.

  1. 01Start with 1 cm/s.
  2. 02Multiply by the conversion factor: 1 × 10 = 10 mm/s.
Result1 cm/s = 10 mm/s

FAQ

What is the conversion factor from cm/s to mm/s?
1 cm/s equals 10 mm/s. To convert, multiply the value in centimetres per second by 10.
How do I convert 1 cm/s to mm/s?
1 cm/s = 10 mm/s. For any value, multiply by 10.
How do I convert mm/s back to cm/s?
Divide by the same factor — or equivalently, multiply by 0.1. So 1 mm/s = 0.1 cm/s.
When would I need to convert centimetre 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).
