About Torque Converter
The Torque Converter changes a rotational-force value between every common torque unit at once.
Enter a figure in newton-metres, pound-feet, pound-inches, kilonewton-metres, kilogram-force metres or ounce-inches, choose the unit you started in, and the tool instantly shows the equivalent in all of the others.
Torque is the twisting force that tightens a bolt, spins an engine or drives a motor, and the world stubbornly uses different units for it: a workshop manual might specify N·m, a North American spec sheet lists lb·ft, small fasteners and electronics are rated in lb·in or oz·in, and older European literature still uses kgf·m.
Mixing them up can mean an under- or over-torqued joint, so a reliable conversion matters.
Every result is computed from a single SI pivot — the newton-metre — using exact definitional factors (one pound-foot is 1.3558179483 N·m, one kgf·m is 9.80665 N·m), so the numbers match engineering references rather than rough approximations.
Negative values are accepted to represent direction.
Nothing is uploaded; the maths happens locally in your browser, so it is fast, private and works offline once loaded.

FAQ
How many newton-metres is one pound-foot?
One pound-foot equals 1.3558179483 newton-metres. The tool uses this exact factor, derived from the standard pound-force and the foot.
What is the difference between pound-foot and foot-pound?
For torque they are the same magnitude; "pound-foot" (lb·ft) is the preferred name for torque, while foot-pound usually denotes energy. The numeric conversion is identical.
Can I enter negative torque?
Yes. A negative sign just indicates the opposite rotational direction, so negative values convert normally.
