Viscosity – Kinematic Converter

A comprehensive kinematic viscosity converter displaying all 11 units simultaneously. SI units: m²/s (base SI unit), m²/h, mm²/s (= centistokes, cSt), and dm²/s. CGS units: cm²/s (= 1 Stokes, St), Centistokes (cSt = 1 mm²/s), and Stokes (St = 1 cm²/s). Imperial units: ft²/s, ft²/h, in²/s, and in²/h. Kinematic viscosity = dynamic viscosity ÷ density. Water at 20°C = 1 cSt; engine oil SAE 30 ≈ 100–120 cSt; gasoline ≈ 0.4–0.8 cSt; air at 20°C ≈ 15.1 cSt. Includes these reference values in a collapsible panel. Click any row to use it as the new input for reverse conversion. Adjustable significant figures (3–12) and scientific notation toggle. All conversions are instantaneous and browser-based.
