Water Viscosity Calculator

Calculate the dynamic and kinematic viscosity of water at different temperatures

Input Parameters

Temperature (°C)

0°C 20°C 40°C 60°C 80°C 100°C

Selected Value:

Pressure (atm)

Note: Water viscosity is primarily affected by temperature. Pressure has minimal effect under normal conditions.

Dynamic viscosity (μ) is a measure of a fluid’s resistance to flow. For water, it decreases as temperature increases.

Unit: mPa·s (millipascal-seconds) or cP (centipoise)

Kinematic viscosity (ν) is the ratio of dynamic viscosity to density. It represents the fluid’s resistance to flow under gravity.

Unit: mm²/s (square millimeters per second)
