How many kilowatt-hours is 1 foot-pound?

1 foot-pound (ft·lbf) equals approximately 3.76616×10⁻⁷ kWh. This comes from: 1 ft·lbf = 1.35582 joules, and 1 kWh = 3,600,000 joules, so 1.35582 ÷ 3,600,000 ≈ 3.76616×10⁻⁷ kWh.

How do I convert foot-pounds to kilowatt-hours manually?

Multiply the foot-pound value by 3.76616×10⁻⁷. For example, 1,000,000 ft·lbf × 3.76616×10⁻⁷ ≈ 0.376616 kWh. To reverse, divide the kWh value by 3.76616×10⁻⁷ (or multiply by 2,655,224).

What is a foot-pound and what is a kilowatt-hour?

A foot-pound (ft·lbf) is the work done by a one-pound force acting over one foot — equal to about 1.35582 joules. A kilowatt-hour (kWh) is the energy used by a 1-kilowatt device running for one hour — exactly 3,600,000 joules. Foot-pounds are common in mechanical engineering and ballistics in the US; kWh is the standard unit on electricity bills.

Why are so many foot-pounds needed to make one kilowatt-hour?

Because a foot-pound is a very small unit of energy by electrical standards. One kWh equals roughly 2,655,224 ft·lbf. For context, a 100-watt light bulb running for one hour uses 1 kWh — the same energy as lifting a 1-pound weight about 2.5 million feet.

Is foot-pound the same as pound-foot?

In everyday use the terms are often swapped, but technically they differ: foot-pound (ft·lbf) is an energy/work unit; pound-foot (lbf·ft) is a torque unit. They have the same numerical magnitude but different physical meanings. This converter uses the energy definition (ft·lbf).
