Torque Converter
Enter a torque value and choose your source and target units to convert instantly between foot-pounds, inch-pounds, newton-meters, and kilogram-force meters — common when working with torque wrench specs from different regions or manuals.
How the Torque Converter formula works
Every unit routes through newton-meters as a common base:
value_in_Nm = value × factor_of_source_unit result = value_in_Nm / factor_of_target_unit
For example, 1 ft-lb = 1.35582 Nm and 1 kgf-m = 9.80665 Nm.
Step-by-step calculation
- Multiply the entered value by its unit's conversion factor to get newton-meters.
- Divide that value by the target unit's conversion factor.
- Round to a sensible number of decimal places.
Worked example
Converting 25 ft-lb to Nm: 25 × 1.35582 ≈ 33.9 Nm — a common torque spec conversion when a manual lists values in one unit and your torque wrench is calibrated in another.
Frequently asked questions
Why do torque specs sometimes use different units in different manuals?
Regional and industry conventions differ — US automotive specs often use ft-lb, smaller fasteners are often specified in in-lb, and metric or international specs typically use Nm, so conversion is frequently needed when working across sources.
