Torque measures rotational (twisting) force, and shows up everywhere from car engine specifications to the tightening specs printed on bolts and lug nuts.
Different regions and industries default to different units — metric newton-meters versus imperial pound-feet and pound-inches — which makes a quick converter genuinely useful for anyone reading a torque wrench spec or an engine spec sheet.
How it works
Enter a torque value, choose the unit you're converting from, and the unit you want to convert to. The tool applies the standard conversion factors between newton-meters, pound-feet, pound-inches, and kilogram-force meters and returns the result.
- Enter value.
- Enter from.

Examples
Reading a lug nut torque spec
A lug nut spec of 100 pound-feet converts to about 135.58 newton-meters on a metric torque wrench.
Who should use it
- Converting a manufacturer's torque spec to match the units on your own torque wrench.
- Comparing engine or fastener specifications published in different unit systems.
Industry applications
- Automotive repair and manufacturing
- Mechanical and structural engineering
Advantages
- Covers the four most common torque units used in mechanical and automotive specifications.
- Exact, standards-based conversion factors.
Common mistakes to avoid
- Using a pound-feet spec on a newton-meter torque wrench without converting first, resulting in significant over- or under-tightening.
- Confusing pound-feet and pound-inches, which differ by a factor of 12.
Best practices
- Always confirm which unit your torque wrench is set to before applying a spec from a manual written in a different unit.
Tips
- When a repair manual and your tool use different units, convert and double-check the number before applying force to a fastener — over-torquing is a common and costly mistake.
