Water Viscosity vs Temperature Calculator
Dynamic and kinematic viscosity of water at any temperature 0–100 °C (Vogel equation).
Water at 80 °C flows with ⅓ the viscosity of 20 °C water — pumping hot water saves real friction head. Fit accurate to ±1% over 0–100 °C.
Formula
Water Viscosity vs Temperature Calculator is a free water viscosity temperature for process, mechanical and water engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Water Viscosity vs Temperature Calculator

Frequently asked questions
What formula does the Water Viscosity vs Temperature Calculator use?+
It computes μ(T) = e^(−3.7188 + 578.919/(T−137.546)) Pa·s (Vogel fit), per Vogel equation fit to IAPWS data. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Water at 80 °C flows with ⅓ the viscosity of 20 °C water — pumping hot water saves real friction head. Fit accurate to ±1% over 0–100 °C.
Does this work for any fluid?+
Yes — density and viscosity are inputs (with common fluids suggested in the field hints), so the same physics applies to water, oils, gases and process fluids. Compute always runs in SI internally, so unit mix-ups can't corrupt the result.
Is the Water Viscosity vs Temperature Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
