Best Answer

No. BTUs are heat (British Thermal Units) and cfm is a measure of air flow volume (cubic feet per minute)

Calories x 0.003968 = BTU


How do you convert BTU's in CFM?

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 know 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: Qsens = cfm * 1.08 * (Tin - Tout) <-- "delta T" You need to determine what your "delta T" is. For cooling a space to 75degF, your dT is usually 20degF with your supply air temperature (SA=55) and your return air temperature (RA=75). This has been idealized and simplified. For cooling, 1cfm will do about 21.6btu/h of cooling. For heating, (SA=90, RA=68, 1cfm => 23.76btu/h)


How do you convert MMSCFD to CFM?

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 multiplying 60 by 24 and then dividing the MMSCFD by this product.


How do you compute BTU of a heater using CFM and output temperature?

I'm not sure and will have to research this, but let me kick it off by writing Btus/hr = CFM X 1.08 X temperature rise. Hopefully, others will weigh in and contribute further to this answer. (Since I supervise Units and Unit Conversions, I would like to admonish people to use the units Btus/hr, not just Btus, when referring to power.)
