To convert cmh to cfm .....
divide cmh by 1.7 to convert into cfm....
400x0.5883
Cmh = cubic meters per hour cfm = cubic feet per minute m3/hr * 35.3ft3/m3 * hr/60minutes = ft3/minute So, 1 cmh = 0.5883 cfm
The relationship between cubic feet per minute or cfm and cubic meter per hour or cmh is that there are approximately 0.59 cfm in 1 cmh. Similarly, 1 cfm is equal to approximately 1.7 cmh.
cfm is less than cmh by by 40% (approximately)
"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
Tr = cfm/400
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
divide by 60
You can do it with two steps. first convert kmh to cmh (centimeter per hour) by duplicate it by 1000. then, convert the cmh to cms (centimeter per second) by divide it by 3600. in other words, you can just multiply the kmh by (10/36) and get the equal value with cms units.
1,000 cfm (feet3/min) is 0.4719474 m3/sec.
Get it CMH Calculation
No. BTUs are heat (British Thermal Units) and cfm is a measure of air flow volume (cubic feet per minute)
CMH Records was created in 1975.
