Viscosity Converter

Dynamic (absolute) viscosity measures a fluid's resistance to shear. Unit: Pa·s. Water at 20°C ≈ 1 cP = 1 mPa·s.

A combined viscosity converter covering both dynamic (absolute) and kinematic viscosity in one tool. Switch between Dynamic and Kinematic tabs. Dynamic viscosity units include Pa·s, mPa·s, μPa·s, N·s/m², kg/(m·s), kgf·s/m², Poise (P), Centipoise (cP), dyn·s/cm², g/(cm·s), lbf·s/ft², lbf·s/in², lb/(ft·s), and lb/(ft·h). Kinematic viscosity units include m²/s, m²/h, mm²/s (cSt), cm²/s (St), Centistokes, Stokes, ft²/s, ft²/h, and in²/s. All conversions are shown simultaneously. Adjustable significant figures and scientific notation toggle. Includes reference values for common fluids (water, engine oil, honey, gasoline, air). All calculations are instantaneous and browser-based.

How to Use

  1. 1Click Dynamic tab for absolute viscosity, or Kinematic for flow viscosity
