Convert Pound-feet to Kilonewton-meters
lb·ft to kN·m · torque conversion
What are pound-feet and kilonewton-meters?
A pound-foot is the imperial torque unit, standard for US car engine specs. A kilonewton-meter is 1,000 newton-meters, used in heavy engineering. For reference: car lug nuts are often torqued to around 120 N·m (about 89 lb·ft).
How to convert pound-feet to kilonewton-meters
1 lb·ft = 0.00135582 kN·m. To convert, multiply the number of pound-feet by 0.00135582. For example, 5 lb·ft = 0.00677909 kN·m, and 20 lb·ft = 0.0271164 kN·m. To go the other way, multiply kilonewton-meters by 737.562 (since 1 kN·m = 737.562 lb·ft).

FAQ
What is 1 lb·ft in kN·m?
1 lb·ft = 0.00135582 kN·m. To convert any amount, multiply the number of pound-feet by 0.00135582.
How do I convert kilonewton-meters back to pound-feet?
Go the other way: 1 kN·m = 737.562 lb·ft, so multiply kilonewton-meters by 737.562 to get pound-feet.
Is a pound-feet bigger than a kilonewton-meter?
No — 1 lb·ft is the smaller unit, equal to 0.00135582 kN·m (it takes 737.562 lb·ft to make one kN·m).
Are these torque conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
