Torque Converter

Runs locally in your browser. Nothing leaves your device.

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.

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.

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.
