Nm to Ft-Lbs Converter
1 Nm is about 0.7376 ft-lbs, so a 100 Nm torque spec equals 73.76 ft-lbs. This nm to ft lbs converter switches between newton-meters, foot-pounds, and inch-pounds in either direction. Use it to read a torque wrench spec, follow a repair manual, or match a metric bolt rating to imperial tools.
Quick answer
1 foot-pound is exactly 1.3558179483 newton-meters.
Result
73.756215 ftlb
What this tells you
- •1 foot-pound is exactly 1.3558179483 newton-meters.

How It Works
Formula
ft-lbs = Nm / 1.3558179483One foot-pound is defined as exactly 1.3558179483 newton-meters, so divide newton-meters by that factor to get foot-pounds. Going the other way, multiply foot-pounds by 1.3558179483. Inch-pounds are one twelfth of a foot-pound, useful for small fasteners.

Worked Examples
Convert 100 Nm to ft-lbs
Divide 100 by 1.3558179483 to get about 73.76 ft-lbs.
Convert 50 ft-lbs to Nm
Multiply 50 by 1.3558179483 to get about 67.79 Nm.
Newton-meters to Foot-pounds Conversions
Common torque values, rounded to 2 decimal places.
| Newton-meters | Foot-pounds |
|---|---|
| 1 Nm | 0.74 ft-lb |
| 10 Nm | 7.38 ft-lb |
| 25 Nm | 18.44 ft-lb |
| 50 Nm | 36.88 ft-lb |
| 100 Nm | 73.76 ft-lb |
| 200 Nm | 147.51 ft-lb |
Common mistakes
- Multiplying instead of dividing when going from Nm to ft-lbs. Newton-meters are smaller, so the ft-lb number is always lower.
- Rounding the factor to 1.36. Over a tight bolt spec that error can push the torque out of range.
- Mixing up foot-pounds and inch-pounds. There are 12 inch-pounds in a foot-pound, so a spec in in-lb is 12 times larger.
