About Converting Pound-inches to Kilonewton meters
Pound-inch and Kilonewton meter both measure torque, and the conversion is essential for anyone using a torque wrench specified in one unit against a bolt or engine spec given in the other. Specifically: Torque from one pound-force at one inch, and kilonewton meter is 1000 newton meter units.
Formula
kilonewton meters = pound-inches × 0.000112984829028
This factor comes from each unit's defined relationship to the category's base unit: 1 pound-inch equals 0.112984829028 base units, and 1 kilonewton meter equals 1000 base units, so dividing one by the other gives the direct pound-inch-to-kilonewton meter factor of 0.000112984829028.
Simple example
1 lb in × 0.000112984829 = 0.0001129848 kN m
1 pound-inch = 0.0001129848 kilonewton meters.
Real-world example
10 lb in × 0.000112984829 = 0.0011298483 kN m
10 pound-inches = 0.0011298483 kilonewton meters.
