### How many BTU does it take to heat a cubic foot of air?

It takes 0.24 BTU of heat to change the temperature of one pound of air by one degree F. The 1.08 factor also contains the specific density of air (0.075 pounds per cubic foot). The air is measured in CFM, yet the specific heat is per pound of air.

How do you calculate BTU heat?

For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.

How do you calculate BTU of gas?

Computing BTUH: Technical Note: you can compute the BTU’s per hour of gas consumption of your gas-fired equipment. Making sure than only a single gas appliance is running, watch the gas meter and measure the time required to use one cubic foot of gas. The formula: (3600 x 1000)/seconds = BTUH.

#### How many cubic feet is 1 MMBtu?

The answer is: 1 mmBTU equals 1,000.00 cu ft N.G.
