Convert Newton-meters to Pound-inches
N·m to lb·in · torque conversion
What are newton-meters and pound-inches?
The newton-meter is the SI unit of torque, one newton applied one meter from the pivot. A pound-inch is 1/12 of a pound-foot, used for small fasteners and electronics. For reference: car lug nuts are often torqued to around 120 N·m (about 89 lb·ft).
How to convert newton-meters to pound-inches
1 N·m = 8.85075 lb·in. To convert, multiply the number of newton-meters by 8.85075. For example, 5 N·m = 44.2537 lb·in, and 20 N·m = 177.015 lb·in. To go the other way, multiply pound-inches by 0.112985 (since 1 lb·in = 0.112985 N·m).

FAQ
What is 1 N·m in lb·in?
1 N·m = 8.85075 lb·in. To convert any amount, multiply the number of newton-meters by 8.85075.
How do I convert pound-inches back to newton-meters?
Go the other way: 1 lb·in = 0.112985 N·m, so multiply pound-inches by 0.112985 to get newton-meters.
Is a newton-meter bigger than a pound-inche?
Yes — 1 N·m is the larger unit, equal to 8.85075 lb·in.
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.
