What is Torque Converter?

Torque Converter lets you quickly convert between Newton-meters, pound-feet, kilogram-force meters, and other torque units. Enter a value in any unit and see instant conversions across all common torque measurements.

The converter spans eleven units, from the millinewton-metres and newton-centimetres used in precision instruments and servo motors up through newton-metres, kilonewton-metres for heavy machinery, pound-feet, kilogram-force metres, inch-pounds, ounce-inches, kilogram-force centimetres, gram-force centimetres, and dyne-centimetres. A logarithmic magnitude chart shows just how far apart those unit sizes really are. There is also a torque-from-force calculator: type the force on a wrench and the length of the lever arm, and it works out the torque you are applying, plus a power readout that turns any torque into horsepower, PS, and kilowatts at common engine speeds. Quick references list typical fastener specs for cars, bikes, motorcycles, and industrial flanges at a glance.

How to use

1. Enter a torque value in the input field.
2. Select the source unit from the dropdown (N·m, lb·ft, kgf·m, etc.).
3. View the converted values in all supported torque units displayed below.

When to use

• Following a workshop manual that lists fastener specs in lb·ft while your torque wrench reads N·m.
• Converting JIS spec sheets from kgf·m into pound-feet for a US-market technician.
• Checking that a small servo motor datasheet's mN·m rating matches your robotics project's needs.

Result

A mechanic converting a bolt specification from 95 N·m to see it equals approximately 70.1 lb·ft for their torque wrench.

FAQ

What's the difference between N·m and lb·ft?

Both measure rotational force but use different base units. One pound-foot equals about 1.356 newton-metres, so a 100 lb·ft spec becomes roughly 135.6 N·m. The wrench you use determines which one matters for a given job.

Is kgf·m the same as kg·m?

Almost. Kgf·m means kilogram-force times metre, where one kilogram-force is the weight (gravity) of one kilogram of mass on Earth. So 1 kgf·m equals 9.80665 N·m. Plain kg·m is dimensionally incorrect for torque.

Why is dyne-centimetre such a tiny unit?

It comes from the CGS system used in physics. One dyne is the force needed to accelerate a one-gram mass by one centimetre per second squared. That gives a torque scale ten million times smaller than the SI newton-metre.

Do I need to worry about clockwise vs counter-clockwise torque?

The numbers are the same; sign just denotes direction. Most workshop specs assume tightening (clockwise for right-handed threads). Reverse-threaded fasteners on lawnmower blades and some pulleys flip that convention.

How do I convert torque numbers from older Japanese service manuals?

JIS manuals often list values in kgf·m. Multiply by 9.80665 to get N·m, or by 7.233 to get pound-feet. The Quick Reference panel in this tool shows common motorcycle and car fastener ranges so you can sanity-check the result.
