Convert newton-meter to foot-pound (pound-foot).
To convert newton-meters to foot-pounds, multiply by 0.737562. 1 N·m = 0.7376 ft·lb and 1 ft·lb = 1.3558 N·m. Example: an M10 class 8.8 bolt at 53 N·m needs 39.1 ft·lb. Ft·lb and lb·ft are the same torque unit.

Tips & tricks
- Quick estimate: N·m × 0.74, or N·m × 3 ÷ 4.
- Ft·lb, ft-lb, lb·ft and lb-ft all mean the same torque unit.
- For small fasteners, use inch-pounds: 1 N·m = 8.8507 in·lb.
- Ft·lbf is also an energy unit (work). This page converts torque. For energy, use the ft·lbf to joule converter.
What is a newton-meter?
One newton-meter (N·m) is the torque from a force of one newton at a lever arm of one meter. It is the SI unit of torque. Metric service manuals and bolt torque charts use N·m.
What is a foot-pound?
One foot-pound (ft·lb or lb·ft) is the torque from a force of one pound-force at a lever arm of one foot. It equals 1.35582 N·m. Most US torque wrenches read ft·lb.
Frequently asked questions
How many ft-lb is 1 Nm?
1 N·m is 0.737562 ft·lb. Multiply the N·m value by 0.737562.
Which is bigger, N·m or ft·lb?
One ft·lb is bigger. 1 ft·lb is 1.35582 N·m, so a torque value in N·m is about 1.36 times the value in ft·lb.
What is 100 Nm in ft-lb?
100 N·m is 73.76 ft·lb.
Are ft-lb and lb-ft the same?
Yes, for torque. Engineers often write lb·ft for torque and ft·lb for energy, but torque wrenches and manuals use both names for the same value.
Is the factor exact?
Yes. 1 ft·lb = 0.3048 m × 4.4482216152605 N = 1.3558179483314004 N·m exactly, from the defined foot and pound-force.
