Convert Square Centimeters per Second to m²/s

Formula

m²/s = cm²/s ÷ 10000

Derivation from SI units:

• 1 cm²/s = 10⁻⁴ m²/s = 1 St
• 1 m²/s = 1 m² ÷ 1 s

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

Worked examples

1. A reading of 0.1 cm²/s converts to 0.00001 m²/s.
   0.1 cm²/s × 0.0001 = 0.00001 m²/s
2. A value of 0.5 cm²/s is 0.00005 m²/s.
   0.5 cm²/s × 0.0001 = 0.00005 m²/s

Where it's used

Square Centimeters per Second are used for diffusion coefficients (gases in air ≈ 0.1–0.2 cm²/s), while square meters per second appear in reynolds-number and pipe-flow calculations (Re = vD/ν). Both measure kinematic viscosity (dynamic viscosity divided by density), so the conversion is a fixed factor.
