Kinematic Viscosity Converter
Enter a value once and convert kinematic viscosity between square metres per second, stokes, centistokes and square millimetres per second. Useful for fluid mechanics, lubrication and pipe-flow calculations in engineering coursework.
How to use
- Enter a value or select an option.
- Choose the From and To units — the result updates live.
- Also see the converted values in all units below.
Note: 1 cSt = 1 mm2/s — engine oil grades are often given in cSt at 40C and 100C.
Tips
- Centistokes and mm²/s are the same unit — 1 cSt = 1 mm²/s — so those two results always match.
- Use the Swap button to flip the conversion direction without retyping the value.
- This converts units only; it does not model how a fluid’s viscosity changes with temperature.
Frequently Asked Questions (FAQ)
What does this converter do?
It converts kinematic viscosity between square metres per second, stokes, centistokes, and square millimetres per second — useful for fluid mechanics, lubrication, and pipe-flow calculations in engineering coursework.
How do I use it?
Enter a value, choose the From and To units, and the result updates live. The Swap button flips the direction without retyping, and converted values for all units are shown below.
Are centistokes and mm2/s the same unit?
Yes. 1 cSt equals 1 mm2/s, so those two results always match.
Does it account for temperature changes?
No. It converts units only; it does not model how a fluid's viscosity changes with temperature. Engine oil grades are often given in cSt at 40C and 100C.
