NM to ft-lbs Formula
The following formula is used to convert N·m to ft-lbs.
ft-lbs = Nm * 0.73756
- Where ft-lbs is foot-pounds
- Nm (N·m) is newton meters
To calculate ft-lbs from N·m, multiply the total newton meters (Nm) by 0.73756. To calculate N·m from ft-lbs, divide the total foot-pounds (ft-lbs) by 0.73756.

Definition
Nm (N·m) and ft-lbs are both units of torque representing a force times a distance. Converting between the two is done using the formula ft-lbs = N·m × 0.73756 or conversely, N·m = ft-lbs / 0.73756.
Example Problem
How to convert N·m to ft-lbs?
- First, determine the value of the torque in N·m.
N·m (sometimes written N-m) means newtons times meters. In order to find a torque value, multiply the force in newtons by the length in meters (using the perpendicular lever arm). For this example, we will say our torque measurement is 50 N·m.
- Next, use the formula above to convert the units into ft-lbs.
Using the formula, we find the total foot-pounds of torque to be: 50 × 0.73756 = 36.878 ft-lbs.
FAQ
What is a newton meter? A newton meter is a unit of measure used to describe torque. Torque is a measurement equal to the applied force times the perpendicular distance (lever arm) from the axis of rotation.
Why would you need to convert torque units? As with most engineering problems, the units used by different companies and countries vary. As a result, it's important to convert any unit, including torque units, into the proper unit for the specific application. If you do not convert the N-m into ft-lbs for problems with units of feet and pounds, the end result will be a miscalculation and potential failure of the application.
