How to Convert Pound-force Inches to Newton Meters
The pound-force inch and newton meter are both units of torque. 1 newton meter equals 8.8507457935 pound-force inches. This means to convert pound-force inches to newton meters, you divide by 8.8507457935.
Formula
Step-by-Step Example
Convert 5 lb·in to newton meters:
We need to convert pound-force inches to newton meters
Since 1 N·m = 8.8507457935 lb·in, divide by 8.8507457935
5 ÷ 8.8507457935 = 0.564924145
5 lb·in = 0.564924145 N·m

About These Units
Pound-force Inch (lb·in)
A pound-inch (lb·in) equals 1/12 pound-foot or 0.113 N·m. Standard for fastener torque specs in US: typical bolt 15-100 lb·in, automotive lug nut 80-100 lb·ft. Torque wrenches often calibrated in lb·in for precision work.
Newton Meter (N·m)
The newton meter (N·m) is the SI unit of torque—rotational force times lever arm distance. Standard automotive torque unit worldwide. Typical car: 200-400 N·m, sports car: 500-700 N·m, diesel truck: 1,000-2,500 N·m. Formula: τ = F × r. One N·m = 0.738 lb·ft.
