Square Centimeter per Second (cm²/s)
The square centimetre per second (cm²/s) equals one stokes. It is also the common unit of diffusion coefficients in chemistry.
Symbol: cm²/s (ASCII: cm2/s)
Quantity: kinematic viscosity (dynamic viscosity divided by density)
SI relation: 1 cm²/s = 0.0001 m²/s (exact)
Derivation: 1 cm²/s = 10⁻⁴ m²/s = 1 St
Exact: yes, by definition
Same quantity as stokes (St) : the factor between them is exactly 1.
Typical uses
- Diffusion coefficients (gases in air ≈ 0.1–0.2 cm²/s)
- CGS kinematic viscosity

| Conversion | 1 cm²/s equals | Reverse |
|---|---|---|
| square centimeter per second to centistokes | 100 cSt | centistokes to square centimeter per second |
| square centimeter per second to square meter per second | 0.0001 m²/s | square meter per second to square centimeter per second |
| square centimeter per second to square millimeter per second | 100 mm²/s | square millimeter per second to square centimeter per second |
| square centimeter per second to stokes | 1 St | stokes to square centimeter per second |
| square centimeter per second to square foot per second | 0.001076391042 ft²/s | square foot per second to square centimeter per second |
