How many BTUs are in a cubic foot of LP gas?

• A. 2000
• B. 3000
• C. 2500
• D. 3500

Answer: (C)

Understanding how much heat is released by LP gas per unit volume is key for sizing appliances and gas lines. LP gas (propane) has a higher energy content per cubic foot than natural gas, so when you burn a cubic foot of LP gas you get a heat output of about two and a half thousand BTUs. That higher density means the same volume of propane delivers more heat, which is why equipment and piping are specified using this per-volume BTU value. This per-volume energy content lets you convert gas consumption (volume) into total heat output (BTUs) for proper appliance sizing and fuel delivery.
