Type a value in newton meters to see it in foot-pounds instantly.
1 newton meter (N·m) = 0.737562149 foot-pounds (ft·lb)
1 foot-pound (ft·lb) = 1.35581795 newton meters (N·m)
How to convert newton meters to foot-pounds
Multiply the number of newton meters by 0.737562149, or divide by 1.35581795.
ft·lb = N·m × 0.737562149 (or N·m ÷ 1.35581795)
Example: 100 N·m × 0.737562149 = 73.7562 ft·lb
Wheel lug nuts on passenger cars are typically tightened to 100–140 N·m (74–103 ft·lb). Always use the value from your vehicle’s manual.

About the units
Newton meter (N·m)
The newton meter is the SI unit of torque: a force of one newton applied at a lever arm of one meter.
Foot-pound (ft·lb)
The foot-pound (pound-foot, lb·ft) of torque is one pound-force acting at one foot, about 1.3558 N·m. US torque wrenches and engine specs use it.
Frequently asked questions
How many foot-pounds are in 1 newton meter?
1 newton meter equals 0.737562149 foot-pounds.
How do I convert newton meters to foot-pounds?
Multiply the number of newton meters by 0.737562149, or divide by 1.35581795. For example, 100 N·m × 0.737562149 = 73.7562 ft·lb.
How many newton meters are in 1 foot-pound?
1 foot-pound equals 1.35581795 newton meters.
Is ft-lb the same as lb-ft?
For torque, yes — both mean one pound-force at one foot. Engineers often write lb·ft for torque and ft·lb for energy to tell them apart.
