How many foot-pounds are in one kilowatt-hour?

1 kilowatt-hour (kWh) equals 2,655,223.74 foot-pounds (ft·lbf). This follows from 1 kWh = 3,600,000 J and 1 ft·lbf = 1.35581794833 J.

What is a kilowatt-hour (kWh)?

A kilowatt-hour is the energy used by a one-kilowatt device running for one hour. It equals 3,600,000 joules (3.6 MJ) and is the standard billing unit for household electricity.

What is a foot-pound (ft·lbf)?

A foot-pound is the energy transferred when a one-pound force acts through one foot of displacement. It is used in US automotive torque specs, firearms muzzle energy, and structural impact energy.

How do I convert kWh to foot-pounds manually?

Multiply kilowatt-hours by 2,655,223.74. For example, 0.5 kWh × 2,655,223.74 = 1,327,611.87 ft·lbf.

How do I convert foot-pounds to kWh?

Divide foot-pounds by 2,655,223.74. For example, 1,000,000 ft·lbf ÷ 2,655,223.74 ≈ 0.377 kWh.

Why is this conversion useful?

Electrical energy is measured in kWh while mechanical energy in the US is often expressed in ft·lbf. Converting between them lets you compare battery capacity, motor output, and impact energy across unit systems.

Summary

This converter handles energy between kilowatt-hours (kWh) and foot-pounds force (ft·lbf). One kilowatt-hour equals 3,600,000 joules exactly; dividing by the joule-to-foot-pound ratio (1 ft·lbf = 1.35581794833 J) gives 1 kWh = 2,655,223.74 ft·lbf.
