Square millimeter per second quick reference
| Square millimeter per second | Centistokes | Square foot per second | Square meter per second |
|---|---|---|---|
| 1 mm²/s | = 1 cSt | ≈ 0.00001076391042 ft²/s | = 0.000001 m²/s |
| 10 mm²/s | = 10 cSt | ≈ 0.0001076391042 ft²/s | = 0.00001 m²/s |
| 100 mm²/s | = 100 cSt | ≈ 0.001076391042 ft²/s | = 0.0001 m²/s |
| 1000 mm²/s | = 1000 cSt | ≈ 0.01076391042 ft²/s | = 0.001 m²/s |
Where the square millimeter per second fits
The next larger kinematic viscosity unit is the stokes (St). 1 mm²/s = 0.01 St, and 1 St = 100 mm²/s.
