About Square metres per second

The square metre per second (m²/s) is the SI coherent unit of kinematic viscosity (ν = μ/ρ). Air at 20 °C ≈ 1.516 × 10⁻⁵ m²/s; water at 20 °C ≈ 1.004 × 10⁻⁶ m²/s; glycerol ≈ 1.19 × 10⁻³ m²/s. It is the standard in CFD codes and SI research literature. 1 m²/s = 10⁴ St = 10⁶ cSt.

About Square inches per second

The square inch per second (in²/s) equals 0.0254² = 6.4516 × 10⁻⁴ m²/s. It is the coherent FPS kinematic unit based on the inch, found in US fluid power, hydraulics, and bearing-design references. 1 in²/s = 645.16 cSt = 6.4516 St.
