Square inch per second quick reference
| Square inch per second | Centistokes | Square foot per second | Square meter per second |
|---|---|---|---|
| 1 in²/s | = 645.16 cSt | ≈ 0.006944444444 ft²/s | = 0.00064516 m²/s |
| 10 in²/s | = 6451.6 cSt | ≈ 0.06944444444 ft²/s | = 0.0064516 m²/s |
| 100 in²/s | = 64516 cSt | ≈ 0.6944444444 ft²/s | = 0.064516 m²/s |
| 1000 in²/s | = 645160 cSt | ≈ 6.944444444 ft²/s | = 0.64516 m²/s |
Where the square inch per second fits
The next smaller kinematic viscosity unit is the stokes (St). 1 in²/s = 6.4516 St, and 1 St ≈ 0.15500031 in²/s.
The next larger kinematic viscosity unit is the square foot per second (ft²/s). 1 in²/s ≈ 0.006944444444 ft²/s, and 1 ft²/s = 144 in²/s.
