cm²/stomm²/s

Convert square centimetres per second (cm²/s) to square millimetres per second (mm²/s).

Factor1 cm²/s = 100 mm²/s

Converter

cm²/s

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

Result
100mm²/s

Rendered to 6 significant figures.

Formula

Formula
mm²/s = cm²/s × 100

Multiply any value in square centimetres per second by 100 to obtain the value in square millimetres per second.

Worked example

Convert 1 cm²/s to mm²/s.

  1. 01Start with 1 cm²/s.
  2. 02Multiply by the conversion factor: 1 × 100 = 100 mm²/s.
Result1 cm²/s = 100 mm²/s

FAQ

What is the conversion factor from cm²/s to mm²/s?
1 cm²/s equals 100 mm²/s. To convert, multiply the value in square centimetres per second by 100.
How do I convert 1 cm²/s to mm²/s?
1 cm²/s = 100 mm²/s. For any value, multiply by 100.
How do I convert mm²/s back to cm²/s?
Divide by the same factor — or equivalently, multiply by 0.01. So 1 mm²/s = 0.01 cm²/s.
When would I need to convert square centimetre per second to square millimetre per second?
Kinematic viscosity conversions between cm²/s and mm²/s arise in hydraulic fluid selection, lubricant grading (ISO VG), pipe flow Reynolds number calculations, and fuel-oil specification. Kinematic viscosity equals dynamic viscosity divided by fluid density and cannot be directly compared to dynamic viscosity without that context.
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).
