How do I convert newton-metres to pound-feet?

Multiply newton-metres by 0.737562 to get pound-feet. So 100 N·m ≈ 73.76 lb·ft.

What is

Torque Conversion

Torque (moment of force) is a force applied at a lever arm that tends to cause rotation — one newton-metre is a one-newton force on a one-metre arm (τ = F · r). Torque conversion changes that figure from one unit to another, for example newton-metres to pound-feet. Every torque unit relates to the SI base (the newton-metre) by a single linear factor, so conversion is one multiply and one divide; torque shares dimensions with energy but is a distinct quantity, so it is written N·m and never joules.

Frequently Asked Questions

One pound-force foot (lbf·ft) equals 1.3558179483314 newton-metres exactly, because it is 0.45359237 kg × 9.80665 m/s² × 0.3048 m. To convert pound-feet to newton-metres multiply by 1.3558179; to convert newton-metres to pound-feet multiply by about 0.737562. For example, a torque wrench set to 100 N·m is roughly 73.76 lbf·ft.

One pound-foot is 1.3558179 newton-metres, so to convert N·m to lb·ft multiply by about 0.7376.

To convert newton-metres to pound-force feet, multiply by 0.737562 (the reciprocal of 1.3558179). For smaller fasteners you may want pound-force inches instead: there are 12 lbf·in in a lbf·ft, so multiply newton-metres by about 8.85075 to get pound-inches. AnyTool shows every torque unit at once, so you do not have to pick the factor by hand.

One kilogram-force metre (kgf·m) equals 9.80665 newton-metres exactly — it is the torque of a 1 kgf weight on a 1 m arm, and 1 kgf is defined under standard gravity g₀ = 9.80665 m/s². The smaller kilogram-force centimetre (kgf·cm), common on motorcycle and small-engine spec sheets, is one hundredth of that, 0.0980665 N·m.

One kilogram-force metre is 9.80665 newton-metres exactly, because it uses standard gravity.

AnyTool Torque Converter computes every result locally in JavaScript using exact factors through a newton-metre base. No value is uploaded, there is no tracking, and the page keeps working offline after the first load.

Detailed Explanation

Methodology

How the Torque Converter Works

AnyTool Torque Converter performs every calculation in the browser. Each unit declares a single linear factor relative to a shared newton-metre base — the exact number of newton-metres in one of that unit — so any unit converts to any other through N·m without an N-by-N table. The factors are the internationally-agreed definitions: a kilonewton-metre is 1000 N·m, a newton-centimetre 0.01 N·m, a millinewton-metre 0.001 N·m and a dyne-centimetre 1e-7 N·m. The gravitational units use standard gravity g₀ = 9.80665 m/s², so a kilogram-force metre is exactly 9.80665 N·m, a kilogram-force centimetre 0.0980665 N·m and a gram-force centimetre 9.80665e-5 N·m. The US/Imperial units come from the exact pound and foot definitions: a pound-force foot is 0.45359237 × 9.80665 × 0.3048 = 1.3558179483314 N·m, a pound-force inch is that divided by 12 (0.1129848 N·m), and an ounce-force inch is the pound-inch divided by 16 (0.00706155 N·m). A value is multiplied to newton-metres and then divided into the target unit.

Eleven units spanning SI, metric/gravitational, CGS and US/Imperial systems
The newton-metre is the shared base; each unit is one exact factor
Pound-foot is exact: 1 lbf·ft = 1.3558179 N·m (0.45359237 × 9.80665 × 0.3048)
Kilogram-force metre uses standard gravity: 1 kgf·m = 9.80665 N·m exactly
All arithmetic is client-side JavaScript — no server round-trip

How It Works

All Units, Precision and Reference

A single input is converted into every torque unit at once in a copyable table, with the source and target rows highlighted. A decimals control sets precision from 0 to 10 places, and magnitudes that are very large or very small automatically switch to scientific notation so results stay readable. A formula reference, a common-conversions list and a units-at-a-glance table (showing each unit in newton-metres and which measurement system it belongs to) accompany the converter, plus a note anchoring the everyday pound-foot (≈ 1.356 N·m) and explaining that torque shares dimensions with energy but is written N·m, never joules.

Privacy & Security

Privacy and Offline Use

Because all conversion runs in the browser, no value is sent to a server, there is no account or tracking, and the page works offline after first load. The converter is built on a shared, unit-tested conversion engine that other AnyTool unit converters reuse, so behaviour is consistent across the site.

Torque conversion: in-browser (AnyTool) vs typical online converters
Capability	AnyTool	Typical online converters
Processing	Runs in your browser	Often server-side
Units	11: SI, metric/gravitational, CGS and US/Imperial	Often N·m and lb·ft only
Imperial coverage	lbf·ft, lbf·in and ozf·in	Frequently just lb·ft
Factor accuracy	Exact definitions (lbf·ft = 1.3558179 N·m)	Frequently rounded constants
Two-way input	Edit either field, both update	Usually one-direction with a button
All units at once	Yes, copyable table	Often one target at a time
