Formula and method

lbf·ft = N·m × 0.737562149 N·m = lbf·ft × 1.355817948 Multiply by the source unit’s SI factor to get N·m, then divide by the target unit’s SI factor.

Worked example

100 N·m × 0.737562149 = 73.7562 lbf·ft.

Assumptions and limits

Converts units only and does not recommend tightening torque; use the fastener spec or the bolt torque calculator for that.

Frequently asked questions

How many lbf·ft are in 1 N·m?

1 N·m = 0.737562149 lbf·ft. The factor follows from the SI definitions: 1 lbf·ft = 4.4482216152605 N × 0.3048 m.

How do I convert lbf·ft back to N·m?

Multiply by 1.355817948 (or divide by 0.737562149), or simply switch “From unit” to lbf·ft. For example 10 lbf·ft = 13.5582 N·m.

Are ft-lb and lb-ft the same thing?

For torque, yes: both mean one pound-force acting on a one-foot lever, written strictly as lbf·ft. ft·lbf is also used as a unit of work or energy with the same number but a different meaning; the ft-lb on a torque wrench is the lbf·ft shown here.
