How the conversion works

Multiply by 0.7375621493 to go from joule to foot-pound, or divide by it to go back. Every conversion on this site routes through the SI value (J) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.

Going the other way? foot-pound to joule — 1 ft⋅lb = 1.355817948 J.
