Convert torque units online

Convert N·m, N·cm, lbf·ft, lbf·in, kgf·m. Reference unit: newton metre. Use this to compare values expressed in different units of the same physical quantity. Select the source and destination explicitly; similar-looking unit symbols can have different scales.

How to use it

Paste one numeric value. Review from unit, to unit. Choose Run tool and review the result. Copy or download the output when it matches your requirements.

Options and example settings

Option	Choices / value	Example default
From unit	N·m / N·cm / lbf·ft / lbf·in / kgf·m	N·m
To unit	N·cm / lbf·ft / lbf·in / kgf·m / N·m	N·cm

Calculation method

Multiply the input by its source factor and divide by its destination factor. Reference: newton metre. Factors: N·m = 1 reference units; N·cm = 0.01 reference units; lbf·ft = 1.3558179483314 reference units; lbf·in = 0.11298482902762 reference units; kgf·m = 9.80665 reference units.

Worked examples

Use this to compare values expressed in different units of the same physical quantity. Select the source and destination explicitly; similar-looking unit symbols can have different scales.

Reproducible sample

Settings: From unit: N·m; To unit: N·cm

Input:

With the settings above, the output is:

Output:

{
  "input": 1,
  "from": "N·m",
  "result": 100,
  "to": "N·cm"
}

For this input, “input” is 1; “result” is 100. These are the named fields in the example output.

Limitations and common mistakes

Multiplicative unit conversion only. Enter a finite numeric value; no material, circuit or operating assumptions are inferred.
Inputs are limited to 250,000 characters in total. Invalid input is reported rather than silently corrected.

Frequently asked questions

How can I check the result?

Run the fixed worked example with the documented settings, compare its output, then check your own input format and units before copying a result.

Does this require an account?

No. This bundled tool runs in your browser without a conversion account.

How can I transform torque units online?

Paste one numeric value. Review from unit, to unit. Choose Run tool and review the result. Copy or download the output when it matches your requirements.
