Cfm to cmh

"CFM" and "CMH" are rates of flow, typically of air or other gases, used to describe the capacity of an HVAC or air handling system, or of a fan.

CFM = cubic feet per minute

CMH = cubic meters per hour

(1 ft3/min) x (meter/3.28084 feet)3 x (60 min/hour) = 1.7 m3/hour

1 m3/hour = 0.5886 ft3/min
