About Converting Kilogram-force meters to Pound-inches
Kilogram-force meter and Pound-inch both measure torque, and the conversion is essential for anyone using a torque wrench specified in one unit against a bolt or engine spec given in the other. Kilogram-force meter is most often used for appears on some legacy torque specifications and equipment predating wider adoption of the newton-meter.
Formula
pound-inches = kilogram-force meters × 86.7961662145
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram-force meter equals 9.80665 base units, and 1 pound-inch equals 0.112984829028 base units, so dividing one by the other gives the direct kilogram-force meter-to-pound-inch factor of 86.7961662145.
Simple example
1 kgf m × 86.79616621 = 86.79616621 lb in
1 kilogram-force meter = 86.79616621 pound-inches.
Real-world example
10 kgf m × 86.79616621 = 867.9616621 lb in
10 kilogram-force meters = 867.9616621 pound-inches.

Understanding the Kilogram-force meter
Kilogram-force meter (kgf m) measures torque. The torque produced by one kilogram-force acting at a perpendicular distance of one meter. It is classified as a non-SI unit, deprecated but still encountered.
Where it's used: Can be encountered in some older European and Japanese automotive and mechanical torque specifications
kgf·m vs. N·m. The newton-meter is the modern SI torque unit; kilogram-force meter is the older, gravity-dependent equivalent still occasionally seen on legacy specifications. 1 kgf·m equals exactly 9.80665 N·m.
