Formula
newton-meters = value x unit factor (1 lbf-ft = 1.3558179483314004 N-m, 1 lbf-in = 0.1129848290276167 N-m)Understanding Torque Conversion
Torque is the turning effect of a force at a distance from an axis, expressed as force times length. Car engines and wheel nut specifications use newton-meters in most markets and pound-feet in the US. Small fasteners often quote pound-inches. Although foot-pounds of torque and foot-pounds of energy share a name, they measure different quantities.
Tips and Best Practices
- 1Multiply N-m by 0.7376 to get pound-feet.
- 2Twelve pound-inches make one pound-foot.
- 3Use a torque wrench set in the same unit the manufacturer lists.
Real-World Example
A wheel nut torque of 100 N-m is 100 x 0.737562 = 73.76 lbf-ft. A spec of 120 lbf-in is 120 x 0.112985 = 13.56 N-m.
Common Mistakes to Avoid
- Confusing pound-feet (torque) with foot-pounds of energy.
- Mixing lbf-in and lbf-ft, a factor of 12 error that can strip or crack a bolt.
- Applying a torque value tightened dry to a lubricated thread without checking the specification.
How to Use
- Pick the unit you have in the left selector and the unit you want in the right selector.
- Type a number in either box; the other box updates instantly.
- Use the swap button to reverse the direction and Copy result to copy the answer.
