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
A much easier way is to visit http://www.hvacquick.com/conversions.php where they have a calculater that will easily convert this for you.
the throttle body is rated at 330 cfm
2200 cfm
CFM is a way of saying ft3/min, or cubi feet per minute. It is a measure of the volume of air a fan can move in a minute. Generally speaking, the higher the CFM, the more powerful a fan it is. Or, if you happen to be in the aircraft industry, CFM refers to the company CFM International, a 50-50 joint venture between General Electric of the United States and Snecma in France.
Cubic Feet per Minute (CFM). A measure of how much air moves in a minute, measured in cubic feet (the amount of air which fits inside a box 1 foot wide, one foot high, and one foot long). Most vacuums and fans are rated in terms of CFM. It tells how much air gets moved in a given length of time. More CFM is usually better, but it usually comes at the cost of more noise.
1. ASSUMING AIR DENSITY AND FAN BLADE DIAMETER IS CONSTANT OR THE SAME --THE LATTER (1750 RPM) DELIVERS MORE CFM WHETHER BELT DRIVEN OR DIRECT COUPLED -- SAME HP RATING OF MOTOR. 2. 1250 RPM FAN CAN MATCH THE CFM OF 1750 RPM FAN --- CHANGE OR ADJUST THE PITCH OF 1250 RPM FAN BLADE. 3. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE FAN BLADE. 4. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE WITH BIGGER HORSE POWER.
To convert cmh to cfm ..... divide cmh by 1.7 to convert into 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.

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.
