How do I convert N·m to lbf·ft?

Divide newton-metres by 1.3558179483314. So 110 N·m ÷ 1.355818 ≈ 81.13 lbf·ft. The converter does this instantly and also shows the reverse direction.

How many newton-metres are in one pound-force foot?

Exactly 1.3558179483314 N·m. It comes from one pound-force (4.4482216152605 N) acting at a lever arm of one foot (0.3048 m).

What is the difference between lbf·ft and lbf·in?

They share the same pound-force but a different lever arm. One foot equals twelve inches, so 1 lbf·ft = 12 lbf·in, and 1 lbf·in ≈ 0.112985 N·m.

What is a kgf·m and where is it used?

A kilogram-force metre is one kilogram-force (9.80665 N under standard gravity) acting at one metre. It is common on older European and Japanese vehicle torque specs; 1 kgf·m ≈ 9.80665 N·m ≈ 7.233 lbf·ft.

What is a dyne-centimetre?

It is the CGS unit of torque: one dyne of force at one centimetre. One dyne-centimetre is tiny — exactly 1e-7 (0.0000001) N·m — so it is mostly used in physics rather than mechanics.

Are torque and energy the same because both use N·m?

No. A newton-metre of energy is a joule, but torque is a rotational quantity (force times a perpendicular lever arm), so it is kept as N·m and never written as joules even though the base dimensions match.

Torque Converter — Gera Tools

A torque converter that turns any value between newton-metres (N·m), kilogram-force metres (kgf·m), pound-force feet (lbf·ft), pound-force inches (lbf·in) and dyne-centimetres (dyn·cm). Type one number, choose your From and To units, and the headline updates instantly while the grid below shows the same torque expressed in every supported unit at once. It is built for mechanics reading mixed-unit service manuals, engineers checking a fastener spec, and anyone whose torque wrench is calibrated in different units than the specification they are following.

How it works

Every unit is defined by how many newton-metres sit in one of it, and the tool converts through that single base. When you enter a value it is first turned into newton-metres (value × the From factor) and then divided by the To factor, so all five readouts always stay perfectly consistent. The factors are exact by definition: a pound-force is 4.4482216152605 N, a foot is 0.3048 m and an inch is 0.0254 m, which gives 1 lbf·ft = 1.3558179483314 N·m and 1 lbf·in = 0.1129848290276 N·m. A kilogram-force metre uses standard gravity, 9.80665 N·m, and a dyne-centimetre is exactly 1e-7 N·m. Because foot equals twelve inches, 1 lbf·ft is always exactly 12 lbf·in — a handy sanity check.

Precision adapts to the size of the number, so small fastener torques keep enough decimals while large engine figures stay readable. The swap button flips the From and To units in place, which is the fastest way to bounce between, say, a manual quoted in N·m and a wrench marked in lbf·ft. The grid and the reference table below it let you eyeball several conversions without retyping anything.

Example

A wheel lug nut spec of 110 N·m needs checking on a wrench marked in lbf·ft. Enter 110, set From to N·m and To to lbf·ft: the result is about 81.13 lbf·ft. The grid also shows it as roughly 11.22 kgf·m and 973.6 lbf·in at the same time. Going the other way, 100 lbf·ft comes out as about 135.58 N·m.

From	Value	N·m	lbf·ft	kgf·m
N·m	1	1	0.737562	0.101972
lbf·ft	1	1.355818	1	0.138255
kgf·m	1	9.80665	7.233014	1
lbf·in	1	0.112985	0.083333	0.011521
