💧 Kinematic Viscosity Converter
Convert kinematic viscosity units — square metre per second, square millimetre per second, stokes and centistokes. 1 cSt = 1 mm²/s; oil viscosity grades are given in centistokes.
1 m²/s = 1000000 mm²/s
1 square metres per second = 1000000 square millimetres per second
1 × 1000000 = 1000000
1 m²/s equals 1000000 mm²/s, so multiplying by 1000000 converts the value. The result describes the exact same quantity — only the measuring stick changes.

All kinematic viscosity units
| Unit | Symbol | Definition |
|---|---|---|
| Square metre / second | m²/s | The SI unit of kinematic viscosity — dynamic viscosity divided by density. Most liquids are a tiny fraction of 1 m²/s (water is about 1×10⁻⁶ m²/s). |
| Square millimetre / second | mm²/s | One millionth of a m²/s (10⁻⁶ m²/s), numerically identical to the centistokes. The practical SI unit — water at 20 °C is about 1 mm²/s. |
| Stokes | St | The CGS unit of kinematic viscosity — one square centimetre per second, exactly 10⁻⁴ m²/s. Named after George Stokes. |
| Centistokes | cSt | One-hundredth of a stokes, equal to 1 mm²/s. The standard unit for lubricants — engine oils are typically rated by their centistokes at 40 °C and 100 °C. |
