How do I convert foot-pounds back to newton-metres?

Multiply the foot-pounds by 1.3558179483314. For example, 50 ft·lb × 1.3558179 ≈ 67.79 N·m. Type into the ft·lb field and the N·m value updates.

Is foot-pound the same as pound-foot?

For torque, foot-pound (ft·lb) and pound-foot (lb·ft) refer to the same unit and value. The order of words varies by convention but the magnitude is identical.

Why use the factor 1.3558179483314?

It is the exact conversion: one foot-pound equals 1.3558179483314004 newton-metres, derived from the defined values of the foot, the pound-force and standard gravity.

Where is this conversion used?

Mechanics and engineers use it for wheel-nut and bolt torque specs, since manuals may list newton-metres while a torque wrench reads in foot-pounds, or vice versa.

Torque N·m to ft·lb Converter

This converter changes torque between newton-metres (N·m) and foot-pounds (ft·lb) in both directions. It is most useful for following a torque spec — for example tightening wheel nuts or engine bolts — when your wrench and the manual use different units.

How it works

One foot-pound equals exactly 1.3558179483314 newton-metres, so the conversion is a fixed factor applied either way:

ft·lb = N·m ÷ 1.3558179483314
N·m   = ft·lb × 1.3558179483314

Type a value in either field and the other updates instantly. Note that for torque, “foot-pound” (ft·lb) and “pound-foot” (lb·ft) are the same unit.

Example

Convert 100 N·m: 100 ÷ 1.3558179 ≈ 73.7562 ft·lb. Going back, 73.7562 × 1.3558179 ≈ 100 N·m.

Torque (N·m)	Torque (ft·lb)
10 N·m	7.375621 ft·lb
25 N·m	18.439054 ft·lb
50 N·m	36.878107 ft·lb
100 N·m	73.756215 ft·lb
200 N·m	147.51243 ft·lb
