About this calculator

Dynamic viscosity unit conversions. Water at 20°C ≈ 1 cP = 0.001 Pa·s. Honey: ~10,000 cP at room temp. Glycerin: ~1500 cP. Motor oil: 100-1000 cP depending on grade and temp. Engineering: Pa·s (SI). Chemistry / industry: cP. Old-school physics: poise. 1 cP = 1 mPa·s — these two are functionally interchangeable.

Frequently asked

Common viscosities?+
Water: 1 cP. Olive oil: 80-100 cP. Honey: 10,000 cP. Pancake batter: 2000 cP. Tar: 30,000 cP.
cP vs. mPa·s?+
Identical: 1 cP = 1 mPa·s. Use whichever your discipline prefers.
Kinematic vs. dynamic?+
Dynamic (this calc): Pa·s. Kinematic = dynamic / density (m²/s = stokes). cSt = mm²/s = centistokes.
Temperature effect?+
Liquids: viscosity drops with heat (motor oil at 100°C is much thinner). Gases: opposite — viscosity rises with heat.
Non-Newtonian fluids?+
Viscosity depends on shear rate (ketchup, blood, paint). Single number doesn't capture full behavior.
