How many kgf·m are in one inch-pound?

1 inch-pound (in·lb) equals 0.011521246 kilogram-force meters (kgf·m). This is derived from the international inch (0.0254 m) and the standard pound-force (0.45359237 kgf).

How do I convert inch-pounds to kgf·m?

Multiply the in·lb value by 0.011521246. For example, 100 in·lb × 0.011521246 = 1.1521 kgf·m. This tool performs the calculation automatically.

How do I convert kgf·m back to inch-pounds?

Multiply the kgf·m value by 86.7962. For example, 2 kgf·m × 86.7962 = 173.59 in·lb. Use the kgf·m input field above for instant reverse conversion.

What is a kilogram-force meter (kgf·m)?

A kgf·m is a metric torque unit equal to the torque produced by one kilogram-force acting at one meter from the pivot. It is still common in older machinery, automotive, and appliance manuals from Japan, Korea, and Europe.

What is the difference between in·lb and in·lbf?

In·lb and in·lbf are the same unit — the "f" denotes pound-force to distinguish it from pound-mass, but in torque context both mean inch-pound of force. The numerical value is identical.

Are kgf·m and N·m the same?

No. 1 kgf·m = 9.80665 N·m (standard gravity). They measure the same physical quantity (torque) but use different force units. kgf·m is older metric; N·m is the SI standard today.

Summary

This converter switches torque between inch-pounds (in·lb) and kilogram-force meters (kgf·m). One inch-pound is the torque produced by one pound of force at one inch from the pivot. The conversion factor is exact: 1 in·lb = 0.0254 m × 0.453592 kgf = 0.011521246 kgf·m. Enter any value and the other field updates instantly. A reference table lists common small-engine torque specs in both units.

How it works

Enter an inch-pound value in the in·lb field to see the kgf·m equivalent instantly.
Enter a value in the kgf·m field to reverse-convert back to inch-pounds.
Both fields update in real time as you type — no button press needed.
Click Copy to copy the converted result to your clipboard.
Click any row in the reference table to load that torque value into the converter.
