Therms to Kilowatt-hours (therm to kWh)

Formula

1 therm = 29.3071 kWh

kilowatt-hours = therms × 29.30710702 — reverse: therms = kilowatt-hours × 0.03412141633

The factor is derived from the SI definitions of both units (base unit: J) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

Worked examples

• 5 therm = 146.536 kWh
• 12.5 therm = 366.339 kWh
• 100 therm = 2930.71 kWh
