100 × 0.737562 = 73.7562
Show the working
- 1. Convert 100 Newton-metre (N·m) to N·ms: 100 × 1 = 100.
- 2. Convert to Pound-foot (lbf·ft): 100 ÷ 1.35582 = 73.7562.

Typical torque settings
- Bicycle crank bolt
- 40 N·m
- Wheel nut, car
- 120 N·m
- Small car engine peak
- 200 N·m
- Diesel truck engine
- 2,500 N·m
- Spark plug, engine
- 25 lbf·ft ≈ 34 N·m
- Watch screw
- 0.05 N·m
Good to know: Torque wrenches often show both: 100 N·m ≈ 73.8 lbf·ft — over-tightening by mixing units is a common mistake.
About this tool
Convert torque between N·m, lbf·ft, lbf·in and kgf·m — for car specs, torque wrenches and engineering.
Formula
1 lbf·ft = 1.355818 N·m; 1 lbf·in = 0.1129848 N·m; 1 kgf·m = 9.80665 N·m.
Reference values
- 100 N·m ≈ 73.8 lbf·ft
- 1 lbf·ft = 12 lbf·in
- 1 kgf·m = 9.807 N·m
Questions people ask
How do you convert N·m to lbf·ft?
Divide by 1.355818: 100 N·m ≈ 73.8 lbf·ft. Multiply lbf·ft by 1.355818 to get N·m.
Is lb-ft the same as ft-lb?
For torque, yes — both mean pound-force-feet. "ft-lb" more properly refers to energy (work), the same number with a different meaning.
What is kgf·m?
An older metric unit: 1 kgf·m = 9.80665 N·m. Japanese car manuals often quote torque in kgf·m.

How we calculate this
Torque is force × lever length: SI newton-metres, with pound-foot derived from the pound-force (4.4482216 N) and the exact foot (0.3048 m). Source: BIPM (SI Brochure).
