BTU to CFM to CFH How To Calculate CFM or CFH from BTU per Hr for a Thermal Mass Flow Meter The most common unit for measuring natural gas is the therm. A therm is 100,000 British Thermal Units (BTUs), a quantity of energy, and it is also equal to 29.3 kilowatt-hours or 105.5 mega-joules. A therm's worth of natural gas -Pipe Wrench 8” - Can be used to disassemble gas train assembly. (Part 4A497 from Grainger)-Ratcheting Box Wrench - Can be used to remove orifice and bolts. (size 7/16” and 3/8”) (Part 1AMW9 from Grainger)-6” Steel Rule - Used for measuring air orifice size. (Part 6C289 from Grainger)-Terminals 1/4” Female - Extra female spade terminals. is desired, divide the BTU/HR load by 2488 to get SCFH. Conversely, the BTU/HR capacity can be obtained from SCFH by multiplying the SCFH figure by 2488. Figuring the total load accurately is most important because of the size of the pipe and tubing, the tank (or the number of cylinders), and the regulator will be based on the capac-
