Convert Square Centimeters per Second to Centistokes

Formula

cSt = cm²/s × 100

Derivation from SI units:

• 1 cm²/s = 10⁻⁴ m²/s = 1 St
• 1 cSt = 0.01 St = 10⁻⁶ m²/s = 1 mm²/s
• 1 cm²/s = 0.0001 m²/s ÷ 0.000001 m²/s per cSt = 100 cSt

Both units are defined exactly, so the factor is exact. Square Centimeter per Second definition: square centimeter per second; Centistokes definition: centistokes.

Worked examples

1. A reading of 0.1 cm²/s converts to 10 cSt.
   0.1 cm²/s × 100 = 10 cSt
2. A value of 0.5 cm²/s is 50 cSt.
   0.5 cm²/s × 100 = 50 cSt

Where it's used

Square Centimeters per Second are used for diffusion coefficients (gases in air ≈ 0.1–0.2 cm²/s), while centistokes appear in oil and lubricant viscosity. Both measure kinematic viscosity (dynamic viscosity divided by density), so the conversion is a fixed factor.
