Tightening figures in someone else's units

Converts torque between newton metres, kilogram-force metres, pound-feet and pound-inches.

The newton metre is the SI unit and nearly every European manual uses it. American manuals give pound-feet, and older Russian literature gives kilogram-force metres, often shortened to 'kilogrammetres'.

The confusion is expensive: one pound-foot is 1.36 newton metres while one kilogram-force metre is nearly ten. Reading a figure in kilogram-force metres as the same number of pound-feet under-tightens by a factor of about 7.2; the opposite mistake over-tightens by as much.

How to use

Enter a torque value.
Choose the unit you are converting from: N·m, kgf·m, lbf·ft, lbf·in, ozf·in or dyne·cm.
Choose the unit you are converting to. Below it you get the factors and the same value in the other units.

Newton-metres, pound-feet and kgf·m

A pound-foot is 1.356 N·m and a kilogram-force metre 9.807 N·m. Mistaking kgf·m for lbf·ft is an error of 7.2 times.

Units for small fasteners

A pound-inch is a twelfth of a pound-foot and an ounce-inch a sixteenth of that. They turn up in specifications for small fasteners and electronics.

What to keep in mind

Kilogram-force metres use standard gravity of 9.80665 m/s².
Take tightening torques from the manufacturer's manual, together with any tolerance it gives.

FAQs

How many newton-metres in a pound-foot?

1.3558. In the other direction, one newton-metre is 0.7376 pound-feet.

How is a kilogram-force metre different from a newton-metre?

By a factor of 9.80665. Ten newton-metres is about one kilogram-force metre.

How do I convert a wheel-nut torque from N·m to lbf·ft?

Multiply by 0.7376. If the manual says 120 N·m, that is 88.51 lbf·ft or 12.24 kgf·m. Take the figure for your car from its manual.

How many pound-feet is 100 N·m?

73.76. The same 100 N·m is 10.2 kgf·m.

What is a pound-inch?

A twelfth of a pound-foot. It is used for small fasteners where pound-feet would be too coarse.

If the units match, how is torque different from work?

A newton-metre of torque and a joule of work share dimensions but are different quantities: torque is force on a lever arm, work is force along a path. That is why torque is written in N·m, never joules.

Worked example

A hundred newton metres

Input: 100 N·m into pound-feet

Output: 73.76 pound-feet

Note: The same hundred newton metres is only 10.2 kilogram-force metres. A torque wrench scaled in kgf·m needs that figure, and getting it wrong ends in stripped threads.
