Convert Pound-feet to Newton-meters
lb·ft to N·m · torque conversion
What are pound-feet and newton-meters?
A pound-foot is the imperial torque unit, standard for US car engine specs. The newton-meter is the SI unit of torque, one newton applied one meter from the pivot. For reference: car lug nuts are often torqued to around 120 N·m (about 89 lb·ft).
How to convert pound-feet to newton-meters
1 lb·ft = 1.35582 N·m. To convert, multiply the number of pound-feet by 1.35582. For example, 5 lb·ft = 6.77909 N·m, and 20 lb·ft = 27.1164 N·m. To go the other way, multiply newton-meters by 0.737562 (since 1 N·m = 0.737562 lb·ft).
