Energy uses the SI joule. Food calories (kcal) are 1,000 small calories: 1 kcal = 4,184 J. 1 kWh = 3.6 MJ = 3,600,000 J. 1 BTU = 1,055.06 J.
About Kilowatt-hours and Foot-pounds
Kilowatt-hours (kWh): A thousand watt-hours, or 3.6 MJ; the standard utility billing unit for residential and commercial electricity. Common uses: Electricity bills, residential and EV battery capacity (a typical EV battery is 50-100 kWh), and home solar generation.
Foot-pounds (ft·lb): The work done lifting one pound through one foot against gravity; 1 ft·lb = 1.35582 J. Common uses: Torque specifications in US automotive contexts (lug nuts, bolt torque), and some US engineering work.
How the conversion works
Energy uses the SI joule. Food calories (kcal) are 1,000 small calories: 1 kcal = 4,184 J. 1 kWh = 3.6 MJ = 3,600,000 J. 1 BTU = 1,055.06 J.
The exact relationship is foot-pounds = kilowatt-hours × 2.65521972e+6, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between kilowatt-hours and foot-pounds comes up wherever energy measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
