Convert Kilowatt-hours to Foot-pounds
1 kilowatt-hour is 2,655,223.7374 ft·lbf. One kilowatt-hour is exactly 2655223.7374 foot-pounds.
One kilowatt-hour is 2.6552 × 10^+6 foot-pounds. To convert kilowatt-hours to foot-pounds, multiply by 2.6552 × 10^+6; to go the other way, divide by 2.6552 × 10^+6 or multiply by 3.7662 × 10^-7. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand watt-hours, and the unit every electricity bill is added up in.

How do you convert kilowatt-hours to foot-pounds?
- 1.Take the measurement in kilowatt-hours.
- 2.Multiply by 2.6552 × 10^+6 — that is how many foot-pounds fit in one kilowatt-hour.
- 3.To go back the other way, divide by 2.6552 × 10^+6, or multiply by 3.7662 × 10^-7.
Worked example: 25 kilowatt-hours to foot-pounds
- Formula
- kWh × 2.6552 × 10^+6 = ft·lbf
- Arithmetic
- 25 × 2.6552 × 10^+6 = 66,380,593.435 ft·lbf
- Answer
- 25 kWh = 66,380,593.435 ft·lbf
The factor is rounded for display; the figure above is computed from the full value.

What is a kilowatt-hour?
A thousand watt-hours, and the unit every electricity bill is added up in. Exactly 3.6 megajoules, and the reason a 100 W bulb left on for ten hours costs one unit.
What is a foot-pound?
A pound-force acting through one foot. The same arithmetic as the torque unit of that name, and a different quantity: this one is work done, not twist applied.
How many foot-pounds are in a kilowatt-hour?
One kilowatt-hour is 2.6552 × 10^+6 foot-pounds. Going the other way, one foot-pound is 3.7662 × 10^-7 kilowatt-hours. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
