Approximately how many BTUs are in one cubic foot of natural gas?

• A. 1,000 BTU
• B. 500 BTU
• C. 2,000 BTU
• D. 1,500 BTU

Answer: (A)

Natural gas provides about 1,000 BTU of energy per cubic foot. This approximate value is what engineers use for quick calculations in residential gas systems, though the exact BTU per cubic foot can vary a bit with gas composition and conditions. That’s why 1,000 BTU per cubic foot is the best fit for typical practice. The other options are noticeably outside the common energy content range of standard natural gas: 500 would be much lower than normal, while 1,500 and 2,000 would overstate its energy content.
