When you need to convert British thermal units to kilowatt-hours

  • Comparing food energy labelled in calories with labels in kilojoules.
  • Reading utility bills and appliance ratings that mix kWh, joules and BTU.

Common mistakes to avoid

  • Dividing when you should multiply. Because 1 British thermal unit = 0.000293 kilowatt-hours, the answer should be smaller than the number you started with.
  • Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

  • British thermal unit (BTU): The heat needed to raise one pound of water by 1 °F; used for HVAC in the US. The accepted value is a measured or conventional figure rather than an exact definition, so the factor shown is rounded.
  • Kilowatt-hour (kWh): The billing unit for household electricity. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
