Viscosity

mm²/stocm²/s

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

Factor1 mm²/s = 0.01 cm²/s

Converter

mm²/s

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

Result
1cm²/s

Rendered to 6 significant figures.

Formula

Formula
cm²/s = mm²/s × 0.01

Multiply any value in square millimetres per second by 0.01 to obtain the value in square centimetres per second.

Worked example

Convert 100 mm²/s to cm²/s.

  1. 01Start with 100 mm²/s.
  2. 02Multiply by the conversion factor: 100 × 0.01 = 1 cm²/s.
Result100 mm²/s = 1 cm²/s

FAQ

What is the conversion factor from mm²/s to cm²/s?
1 mm²/s equals 0.01 cm²/s. To convert, multiply the value in square millimetres per second by 0.01.
How do I convert 1 mm²/s to cm²/s?
1 mm²/s = 0.01 cm²/s. For any value, multiply by 0.01.
How do I convert cm²/s back to mm²/s?
Divide by the same factor — or equivalently, multiply by 100. So 1 cm²/s = 100 mm²/s.
When would I need to convert square millimetre per second to square centimetre per second?
Kinematic viscosity conversions between mm²/s and cm²/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).
