About Torque Units

Convert torque between newton-meters, foot-pounds, inch-pounds and kilogram-force meters.

Torque is rotational force: one newton-meter twists with one newton at a one-meter radius. Convert across metric newton-meters, imperial foot-pounds and inch-pounds, and kilogram-force meters used in older manuals.

Always torque critical fasteners (wheels, head bolts) with a calibrated wrench to the manufacturer’s spec in the manual’s units. Everything runs in your browser.

Where it is used

Reading US vs EU car specs, torquing bolts to spec, comparing power tools, and engineering calculations.

How to use the Torque Units

  1. Value — enter the value (e.g. 100).
  2. From — enter the value.
  3. To — enter the value.
  4. Calculate — press the Calculate button to see the result instantly above.

Formula

All units anchored to newton-meters (1 ft-lb ≈ 1.35582 N·m).

Examples

Example

value:100
from:ft-lb
to:Nm
Result: 100 Foot-pounds = 135.582 Newton-meters

Frequently Asked Questions

Torque vs horsepower?
Torque is twisting force; horsepower is how fast that force is applied (torque × RPM / 5252). High torque moves loads, high horsepower sustains speed.
Why do manuals list two torque units?
Global manuals serve metric and imperial markets. Convert, but verify against the primary unit — rounding in printed tables can mislead.
What happens if I over-torque?
Stretched or snapped fasteners, warped parts, and false clamp loads. Under-torque loosens under vibration. Use a torque wrench.
