Drehmoment · lbf·ft → N·m

ft-lbs to Nm Converter (Foot-Pounds to Newton-Meters)

Q: What is 100 lbf·ft in N·m?

100 lbf·ft is 135,58 N·m (100 × 1,3558179).

Q: What is 250 lbf·ft in N·m?

250 lbf·ft is 338,95 N·m (250 × 1,3558179).

Q: How many Nm is 1 ft-lb?

One foot-pound is 1.35582 N·m (1.3558179 to eight figures).

Convert torque in foot-pounds to newton-meters for metric torque wrenches and service manuals. 1 lbf·ft = 1.35582 N·m, so 80 ft-lbs is 108.47 N·m and 100 ft-lbs is 135.58 N·m.

lbf·ft to N·m formula

Kurz gesagt: 1 lbf·ft = 1,3558179 N·m, so multiply by 1,3558179: N·m = lbf·ft × 1,3558179. Going back: lbf·ft = N·m × 0,73756215.

How to convert Pound-Feet to Newtonmeter

A foot-pound of torque is one pound-force (4.4482216 N) acting at one foot (0.3048 m), which is 1.3558179 N·m. Multiply foot-pounds by 1.35582 to get newton-meters. US specs are usually in ft-lbs (or in-lbs for small fasteners); European and Asian manuals use N·m.

1. lbf·ft → N·m

Multiply the number of Pound-Feet by the conversion factor:

N·m = lbf·ft × 1,3558179

Example: 80 lbf·ft × 1,3558179 = 108,47 N·m.

2. N·m → lbf·ft

To go back, divide by the same factor, or multiply by its reciprocal, 0,73756215:

lbf·ft = N·m ÷ 1,3558179

Example: 108,47 N·m ÷ 1,3558179 = 80 lbf·ft.

Mental math: add a third

Add a third of the ft-lbs value. The estimate is under 2% low:

N·m ≈ ft-lbs × 4 ÷ 3

90 ft-lbs: 90 + 30 = 120 N·m (exact: 122.02 N·m).
