Convert Pound-inches to Kilonewton-meters
lb·in to kN·m · torque conversion
What are pound-inches and kilonewton-meters?
A pound-inch is 1/12 of a pound-foot, used for small fasteners and electronics. 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-inches to kilonewton-meters
1 lb·in = 0.000112985 kN·m. To convert, multiply the number of pound-inches by 0.000112985. For example, 5 lb·in = 0.000564924 kN·m, and 20 lb·in = 0.0022597 kN·m. To go the other way, multiply kilonewton-meters by 8,850.75 (since 1 kN·m = 8,850.75 lb·in).

FAQ
What is 1 lb·in in kN·m?
1 lb·in = 0.000112985 kN·m. To convert any amount, multiply the number of pound-inches by 0.000112985.
How do I convert kilonewton-meters back to pound-inches?
Go the other way: 1 kN·m = 8,850.75 lb·in, so multiply kilonewton-meters by 8,850.75 to get pound-inches.
Is a pound-inche bigger than a kilonewton-meter?
No — 1 lb·in is the smaller unit, equal to 0.000112985 kN·m (it takes 8,850.75 lb·in 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.
