Newton metre to Pound-inch

Exact answer: 1 N·m = 8.850745791327 lb·in (exact defined factor)

Newton metre and Pound-inch describe the same quantity from the Torque family but come from different systems of units. The factor is defined exactly. Torque is behind tightening torques, engine data and every bolted joint with a specification.

Examples

011 N·m = 8.850746 lb·in

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 N·m = 8.850745791327 lb·in. Newton metre is the base unit of the family, so the value is converted directly.
