For the sake of comparison, one average cubic foot of natural gas about 1,000 BTU's of heat energy.The chart below shows how much heat energy is released in various quantities of natural gas. HEAT ENERGY PER UNIT OF MEASURE FOR NATURAL GAS UNIT OF MEASURE APPROX.HEAT ENERGY 1 cubic foot 1,000 BTU's 100 cubic feet (1 therm) 100,000 BTU's 1,000 cubic feet (1 mcf) 1,000,000 BTU's.he energy content of natural gas differs in various locations thoughout the country. For the sake of comparison, one average cubic foot of natural gas about 1,000 BTU's of heat energy.The chart below shows how much heat energy is released in various quantities of natural gas.

To convert from BTUs to cubic feet per hour divide BTU by 1100 (example: 50,000 BTU by 1100 = 45.45 cubic feet of gas per hour). See the example on the back of this insert to help further illustrate this.To get BTU from cubic feet, multiply cubic x feet 1100 (45.45 cubic feet x 1100 = 50,000 BTU.).2.aximum gas demand of outlet D-150,000 BTU per hour/1100 BTU per cubic foot = 136.36 cubic feet per hour. 1  The length of pipe from the gas meter to the most remote outlet (outlet A) is 60 feet. 2  Using the column marked 60 feet on the size of gas pipe charge:
