Pa·s Pascal-second SI

SI unit of dynamic viscosity. Equal to 1 kg/(m·s). Water at 20°C ≈ 0.001 Pa·s.

mPa·s Millipascal-second SI

Equal to 1 centipoise. Numerically identical to cP. Water at 20°C ≈ 1.002 mPa·s.

cP Centipoise Metric

Most common practical viscosity unit. Water at 20°C ≈ 1.002 cP. Standard in petroleum and chemical engineering.

P Poise Metric

CGS unit of dynamic viscosity. Equal to 1 g/(cm·s) or 100 centipoise. Named after Jean Poiseuille.

lb/(ft·s) Pound per Foot-Second US

US customary dynamic viscosity unit. Used in some US fluid mechanics references and pipe flow calculations.

lbf·s/ft² Pound-force Second per Square Foot US

US engineering viscosity unit using the gravitational system. Used in some dynamics and tribology references.

kg/(m·s) Kilogram per Meter-Second SI

Equivalent to Pa·s. Directly derived from SI base units.

slug/(ft·s) Slug per Foot-Second US

FPS absolute unit of dynamic viscosity. Used in US dynamics calculations with slug-based mass.

N·s/m² Newton-second per Square Meter SI

Equivalent to Pa·s. An alternative way to express the SI unit of dynamic viscosity.

dyn·s/cm² Dyne-second per Square Centimeter Metric

CGS unit equivalent to 1 Poise. Used in some older scientific and rheological literature.
