About the torque converter

Newton-meters and pound-feet for engines, wrenches, and motors. Pick any two units and the result updates as you type; the exact conversion factor (or formula) is shown beneath the result so you can check it by hand.

How the math works

Linear units convert by one multiplication: the value is scaled by the ratio of the two units' definitions. Factors here follow the SI and NIST SP 81 definitions.

Worked example

  1. Enter the value you have (default 1)
  2. Choose the unit you have in From
  3. Choose the unit you want in To
  4. Read the result and the factor line beneath the board

How to use it

  1. Type a value
  2. Pick the two units
  3. Read the converted result with its exact factor

Frequently asked questions

Is the conversion exact?

Yes — every factor is the exact SI/NIST definition where one exists (for example 1 inch = 25.4 mm exactly). Displayed results are rounded for reading, but the factor line shows full precision.

Why does the number look wrong for very large values?

The result is formatted with fewer decimals as numbers grow. The full-precision value is what the factor line computes.

Can I convert the other direction?

Swap the two dropdowns — the factor line recalculates for the new direction.
