Examples

011 lb·ft = 0.138255 kgf·m

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Torque is not power. Newton metre and hp/kW answer different questions.

03Base unit: N·m

1 lb·ft = 1.35581794833 N·m. Then the value is converted through the base unit N·m into Kilogram-force metre.
