For additional definitions, go toAbsolute (dynamic) and kinematic viscosity. Absolute or dynamic viscosity is used to calculateReynold"s Number to recognize if a fluid flow is laminar, transient or turbulent.

### Online Water Viscosity Calculator

The calculator below can be supplied to calculation the fluid water dynamic or kinematic viscosity at offered temperatures.The calculation dynamic viscosity is offered as cP, mPa*s, Pa*s, N*s/m2,lbf*s/ft2 and lbm/(ft*h),while the kinematic viscosity is offered as cSt, m2/s, and ft2/s

Note! Temperature have to be within the ranges 0-370 °C, 32-700 °F, 273-645 K and 492-1160 °R to obtain valid values.

Temperature

choose the really unit the temperature:

°C °F K °R
