Mass Flow Rate Calculator
Convert volumetric flow to mass flow (kg/s, kg/h, t/day) for process and metering work.
Mass flow is what energy and material balances conserve โ volumetric flow changes with temperature and pressure, แน does not.
Formula
Mass Flow Rate Calculator is a free mass flow rate for process, mechanical and water engineers โ 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.

Frequently asked questions
What formula does the Mass Flow Rate Calculator use?+
It computes แน = ฯยทQ, per Perry's Chemical Engineers' Handbook, ยง6 (fluid dynamics). 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?+
Mass flow is what energy and material balances conserve โ volumetric flow changes with temperature and pressure, แน does not.
Does this work for any fluid?+
Yes โ 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 Mass Flow Rate Calculator free to use?+
Yes โ 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.
