Free Torque Converter

Convert between newton-metres, pound-feet, pound-inches and kilogram-force metres.

What is the Torque Converter?

Convert between newton-metres, pound-feet, pound-inches and kilogram-force metres.

Enter a torque value and pick the units; the tool converts at once. It relies on the exact standard gravity of 9.80665 m/s2, so 1 kgf-m = 9.80665 N-m.

Quick, reliable engineering arithmetic saves time on site and in the workshop. These tools show their working so you can check the result.

How to use the Torque Converter

Using the torque converter takes a minute or two. Your entries are saved in this browser, so you can come back later and carry on.

Step 1

Enter your values, choosing the units you are working in.

Step 2

Read the result and the supporting numbers shown beneath it.

Step 3

Check the result against a second method or a reference table before you rely on it.

Tips for better results

Check the unit on a torque wrench before tightening, because a mix-up between lb-ft and lb-in is a factor of twelve.

Keep units consistent from start to finish.

These tools are for estimates. Safety critical designs need a qualified engineer.
