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.
