A Therm is defined as how many BTU?

• A. 1,000 BTU
• B. 1,000,000 BTU
• C. 10,000 BTU
• D. 100,000 BTU

Answer: (D)

Energy measurement in the gas industry uses a larger unit called a therm, which represents a big chunk of heat energy. By definition, one therm equals 100,000 BTU, which is a convenient size for billing and energy calculations. That’s why the correct answer is 100,000 BTU—it directly matches the standard definition of a therm. For context, 100,000 BTU is about 29.3 kilowatt-hours, so you can also think of a therm as roughly 29 kWh of energy. The other values are simply smaller quantities and do not define a therm.
