British Thermal Unit (BTU) is a measure of energy.
Cubic Feet per Minute (CFM) is a volumetric flow rate.
The flow rate of a material (whether liquid or gas) is dependent on the material.
A volumetric flow rate can be 'adjusted' to a mass flow rate, which is what I think you're really trying to accomplish.
There is no 'direct' conversion from energy units to flow rates (volume or mass); but it is known that some materials can absorb a certain amount of heat energy per unit volume (or mass).
This means the conversion factor is based on the properties of the material in question.
(Volumetric flow rate) = (Heat flow rate) / ((Material Specific heat)*(Material Density)*(Change in Temperature))
Plug in either Imperial or Metric units to obtain the answers you need.

I'm guessing by now you get the idea. The relationship between air flow and heat flow is far more complicated than a conversion factor. Common use of the BTU doesn't help much either since BTU is also often used in place of BTU/hr as in AC sizing. (1 watt is approximately 3.41 BTU/h) Is there a problem you actually trying to solve (i.e. how much will a 50 cfm fan cool a bathroom?)

How do you convert CFM into BTU's?

CFM is a measure of fluid flow, Cubic Feet per Minute.
BTU is a measure of Heat Change.
Heat change depends on the nature of the fluid, that is air is a lot different than water.
Also BTU is a rating of energy that can be delivered by using petroleum products or electricity.
there is no general conversion, it depends on the specifics of your problem

CFM = BTU divided by (1.08 x Temperature Rise)

Dear Everyone,
Could please anyone tell me what is the conversion of 12,000 Btu to cfm?
Someone told me the conversion would be about 400 to 450 cfm!
Thank's
