lb·ft to kgf·m · torque conversion
What are pound-feet and kilogram-force-meters?
A pound-foot is the imperial torque unit, standard for US car engine specs. A kilogram-force-meter is the torque of one kilogram-force at one meter, 9.807 N·m. For reference: car lug nuts are often torqued to around 120 N·m (about 89 lb·ft).
How to convert pound-feet to kilogram-force-meters
1 lb·ft = 0.138255 kgf·m. To convert, multiply the number of pound-feet by 0.138255. For example, 5 lb·ft = 0.691275 kgf·m, and 20 lb·ft = 2.7651 kgf·m. To go the other way, multiply kilogram-force-meters by 7.23301 (since 1 kgf·m = 7.23301 lb·ft).
