About the flow — mass converter

Convert mass flow rate between kg/s (SI), kg/h, g/s, lb/s, lb/min, lb/h, and metric tons per hour. Mass flow describes how much mass passes a point per unit time — essential when fluid density varies, as in compressible-flow and combustion calculations.

Frequently asked questions

  • How many kg/s is 1 lb/s?

    One pound per second equals approximately 0.4536 kg/s.

  • When should I use mass flow instead of volume flow?

    When density changes — e.g. compressible gases or processes where temperature and pressure vary. Mass flow stays constant in steady state; volume flow does not.

  • What is the SI unit of mass flow?

    The kilogram per second (kg/s).
