Kilowatt hour to foot pound converter

Reviewed by the CalculatorHub team, edited by James Graham. Method from NIST SP 811 / BIPM SI. Last verified 2026-06-22.

The Kilowatt hour to foot pound converter computes kilowatt hour to foot pound from the relation ft lb = kWh x 2655223.7373981555. It takes a single input (kilowatt hour in kWh) and returns the foot pound in ft lb. Because this is a pure mathematical or physical formula rather than a jurisdiction-specific rule, the result never changes over time: the same inputs always produce the same answer, so you can rely on it whether you are checking homework, sizing a design, or sanity-checking another tool. Enter your values in the fields below and the result updates instantly; you can also share a permalink that pre-fills the exact calculation, which is useful for teaching, reports, or collaboration. For example, with kilowatt hour = 10 kWh, the foot pound works out to 26552237.373982 ft lb, and the worked example further down the page shows every step so you can follow the arithmetic and reproduce it by hand. The method is the standard form documented by NIST SP 811 / BIPM SI, and the figure above each result carries the date it was last verified.
