ft-lbs to Nm: Convert foot-pounds to newton-meters

Answer
1.35582 N·m = 1 lbf·ft

1 lbf·ft = 1.35582 N·m. To convert foot-pounds to newton-meters, multiply by 1.355817948. To go back, multiply by 0.7375621493 (or divide by 1.355817948). Foot-pounds (ft-lbs, lbf·ft) are the US unit on torque wrenches and in service manuals.

    Formula

    N·m = lbf·ft × 1.355817948 lbf·ft = N·m × 0.7375621493 80 lbf·ft × 1.355817948 = 108.465 N·m
