Foot-Pounds to Newton-Meters Converter
1 ft·lb = 1.35582 N·m. Engine torque: 100 ft·lb = 135.6 N·m. Wheel bolts: ~80 ft·lb = 108 N·m.
Inverse conversion
1 N·m = 0.737562 ft·lb. Wheel bolt torque of 120 N·m = 88.5 ft·lb. Engine: 200 N·m = 147.5 ft·lb.
Formula
Formula
N·m = ft·lb × 1.35582
Worked example
To convert 100 ft·lb to N·m, multiply 100 × 1.35582 = 135.58 N·m.

Unit definitions
Foot-pound (ft·lb)
Foot-pound (ft·lb) is a unit of torque in the imperial system, equal to the torque from a 1-pound force applied 1 foot from the pivot point.
Newton-meter (N·m)
Newton-meter (N·m) is the SI unit of torque. 1 N·m is the torque from a 1-newton force applied 1 meter from the pivot.
