Therms to kWh Calculator
Convert therms of natural gas to kilowatt-hours — and to BTU, ccf, and MMBtu. These are all units of energy, so a therm of gas and a kWh of electricity can be compared directly: 1 therm = 100,000 BTU ≈ 29.3 kWh. Handy for weighing a gas bill against electric, or sizing an electric replacement for a gas appliance.
1 therm = 100,000 BTU ≈ 29.3 kWh · 1 ccf of natural gas ≈ 1.037 therms · 1 MMBtu = 10 therms. These are all energy units — useful for comparing a gas bill (therms/ccf) against electricity (kWh).
