Accuracy and rounding
Use volume-flow conversions only when the fluid volume per time is known; mass flow also depends on density.
Volume-flow units combine fixed volume definitions with fixed time units. U.S. gallons are used when gpm or gph is shown.
For pumps and HVAC, round cfm only after allowing for the equipment tolerance and operating point.
How to convert m³/h to cfm
- Type the m³/h value in the calculator.
- Keep m³/h selected as the from unit and cfm selected as the to unit.

Common questions
How do I convert m³/h to cfm?
Enter the m³/h value in the converter, or multiply by the factor shown in the formula. 1 m³/h = 0.58858 cfm.
What should I watch out for?
GPM and GPH use U.S. liquid gallons; imperial gallons produce a different result.
Where does this flow rate conversion come from?
Volume-per-time factors derived from NIST volume definitions and the SI second. ConverterBase uses stable definitions and fixed conversion factors, not live or rounded market data.
