Torque Converter

Instantly convert torque between N·m, N·cm, N·mm, kgf·m, kgf·cm, lbf·ft, lbf·in, ozf·in and dyn·cm.

Use a comma or period as the decimal separator; do not use thousands separators.

Good to know

The torque converter converts directly in your browser between SI units, practical SI subdivisions, Anglo-American units, technical gravitational force, and CGS, following τ = r × F. Torque and energy share the same dimension but are different physical quantities — joule is therefore deliberately excluded.

Typical searches include Nm to lb-ft, convert torque, and lb-in to Nm. Calculation runs locally in the browser. A force cannot be converted to torque without a lever arm; for fasteners and machines, manufacturer specifications are always authoritative.

Typical use cases

Convert tightening torque for fasteners

Convert lb-ft or lb-in from US workshop manuals into newton-meters to use with metric torque wrenches.

Compare engine and machine specs

Convert torque figures from technical data sheets between different unit systems.

Tips for better results

Don't confuse torque with energy

N·m is torque, joule is energy — both share the same physical dimension but describe different concepts.

Always prefer manufacturer specifications

For fasteners and machines, manufacturer specifications are authoritative — use the converter for conversion, not to derive your own values.

How it works

Step by step

  1. 1

    Enter value and source unit

    Enter the torque value and choose the source unit.

  2. 2

    Choose the target unit

    Choose the target unit from one of the five groups.

  3. 3

    Copy the result

    Copy one or all results for further use.

Features

Five unit groups

SI, practical SI subdivisions, Anglo-American, technical gravitational force, and CGS are separated.

Local conversion

Calculation happens directly in the browser, without transmission to a server.

Torque clearly distinguished from energy

Joule is deliberately excluded to avoid confusion with energy.

Frequently asked questions

Why isn't joule included?

Because torque and energy share a dimension but have different physical meanings — mixing them would lead to misinterpretation.

Are my inputs uploaded?

No. Conversion runs entirely locally in the browser.
