Convert Pound-inches to Newton-meters
lb·in to N·m · torque conversion
What are pound-inches and newton-meters?
A pound-inch is 1/12 of a pound-foot, used for small fasteners and electronics. 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-inches to newton-meters
1 lb·in = 0.112985 N·m. To convert, multiply the number of pound-inches by 0.112985. For example, 5 lb·in = 0.564924 N·m, and 20 lb·in = 2.2597 N·m. To go the other way, multiply newton-meters by 8.85075 (since 1 N·m = 8.85075 lb·in).

FAQ
What is 1 lb·in in N·m?
1 lb·in = 0.112985 N·m. To convert any amount, multiply the number of pound-inches by 0.112985.
How do I convert newton-meters back to pound-inches?
Go the other way: 1 N·m = 8.85075 lb·in, so multiply newton-meters by 8.85075 to get pound-inches.
Is a pound-inche bigger than a newton-meter?
No — 1 lb·in is the smaller unit, equal to 0.112985 N·m (it takes 8.85075 lb·in to make one N·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.
