Nm to ft-lbs Converter

73.8 ft-lb. Multiply Newton-metres by 0.7376 (or divide by 1.3558) to get foot-pounds. Common car figures: 90 Nm = 66 ft-lb, 110 Nm = 81 ft-lb, 140 Nm = 103 ft-lb.

1 foot-pound = 1.355 817 948 Newton-metres exactly (0.3048 m × 4.448 221 615 N), so 1 Nm = 0.737 562 149 ft-lb. The calculator uses the exact value; the table rounds to one decimal.

For torque, yes — mechanics write lb-ft, engineers write ft-lb, and torque wrenches are labelled either way. Strictly, foot-pound is also a unit of energy (work), which is why some standards prefer lb-ft for torque to avoid the clash.

There are 12 inch-pounds in a foot-pound, so 100 Nm = 73.8 ft-lb = 885 in-lb. Small fasteners (bike stems, electronics, cylinder-head covers) are usually specified in in-lb or Nm because the values are too small for a ft-lb wrench to set accurately.

Manufacturers round each unit to a convenient number: a spec of 110 Nm (81 ft-lb) may appear as 80 ft-lb elsewhere. The difference is about 1 %, far less than the ±4 % accuracy of a typical click wrench.
