Accuracy and rounding
For ventilation, fans, compressors, HVAC, and air-handling specifications.
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 m³/h only after allowing for the equipment tolerance and operating point.
How to convert cfm to m³/h
- Enter the value in cfm.
- Select cfm as the source unit.
- Select m³/h as the target unit.
- Read or copy the result.

Common questions
How do I convert cfm to m³/h?
Enter the cfm value in the converter, or multiply by the factor shown in the formula. 1 cfm = 1.699 m³/h.
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.
