How can you convert btu to cfm?
No. BTUs are heat (British Thermal Units) and cfm is a measure of air flow volume (cubic feet per minute)

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.
You can't. Pascals (pa) area messurement of pressure. CFM (cubic feet per minute) is a rate of flow. However, there is a device called a manometer which is used to measure ei…ther pressure(in pascals) or air flow in(in cubic feet). Most commonly used for blower door tests.
Cmh = cubic meters per hour cfm = cubic feet per minute m 3 /hr * 35.3ft 3 /m 3 * hr/60minutes = ft 3 /minute So, 1 cmh = 0.5883 cfm
We're going out on a limb here, taking a chance, throwing caution to the wind, risking looking stupid, and assuming that 'CFM' means 'cubic feet per minute' and 'CMH' mean…s 'cubic meters per hour'. ( 1 ft 3 / min ) x x (1,440 min / hour) / (35.3147 ft 3 / m 3 ) = 40.776 CMH (rounded)
The answer depends on many things.... A btu is a british thermal unit, which is the measure of energy to raise one CC of water one degree Celcius. But you probably want to kno…w about airflow in cfm (not water), and the amount of cooling (or heating) available in 1 cfm or airflow. In Houston, we tend to cool things more than heat. We also try to drive moisture out of the air (dehumidify), but I won't discuss that now. The general equation to answer your question is like this: Q sens = cfm * 1.08 * (T in - T out ) 23.76btu/h)
If you know the FPM and you know the area of your flow say duct work (20"x20")... first convert your area 20*20=400 in 2 to Ft 2 20"*20" = 400in 2 400…in 2 /144 = 2.7777Ft 2 Now that you know the area in Ft 2 you can use the equation [ FPM*area(ft 2 ) = CFM ] if your FPM is 500 and we use the 20"x20" duct then 500fpm * 2.777Ft2 = 1388.5 cfm
The two are related but are not equivalents. 12000 btu = 1 ton of refrigeration , in a typical air conditioning application 400 cfm per ton are needed to properly support it`s… operation.
No: CFM is Cubic Feet per Minute, which is a flow rate (volume/time). PSI is Pounds per Square Inch, which is a pressure measurement (force/area). However, for certain situa…tions with known substances moving in a known piping, there may be tables available which at a certain pressure, the the substance will move through the pipe at a certain rate. These would be very specific situations and not a general conversion, though.
have a AC unit that is rated 5,200 CFM's. What is the conversion toBTU's
1bar mens what cfm
kpa = kilopascals is a measure of pressure. cfm = cubic feet per minte is a measure of the rate of flow. The two measure different things and, according to the basic rules o…f dimensional analysis, conversion from one to the other is not valid.
In Math and Arithmetic
15 cfm a 65 cbm
Coverting MMSCFD which is million standard cubic feet per day to CFM or cubic feet per minute requires knowing how many minutes are in a day. This can be determined by multip…lying 60 by 24 and then dividing the MMSCFD by this product.
divide by 60

That all depends on what unit you want to convert it to , which you neglect to mention in your question.
