Formula used
m³/h = CFM × 60 ÷ 35.3146667 = CFM ÷ 0.588577778
The factor 35.3146667 converts cubic meters to cubic feet. Dividing by 60 changes per-hour to per-minute. Multiplying m³/h by 0.588577778 yields CFM.

Unit facts and engineering notes
- 1 m³ = 35.3146667 ft³ by exact SI and imperial definitions.
- 1 m³/h = 0.588577778 CFM (divide m³/h by 1.699010797).
- 1 CFM = 1.699010797 m³/h (multiply by the shown factor).
- Per-minute conversion arises from dividing per-hour values by 60.
- Show three decimals for sizing; increase precision for audits.
- CFM often denotes volumetric flow at actual conditions. Note density changes.
