Torque Converter
Convert between newton-metres, pound-feet and kilogram-force metres.
About this calculator
Torque specifications for engine bolts, wheel lug nuts, and other fasteners are given in whichever unit the manufacturer's region uses, N·m internationally, lb·ft commonly in US automotive contexts, and kgf·m on some older or region-specific torque wrenches, so mechanics working across different manuals or tools regularly need to convert between them accurately since over- or under-torquing a fastener can cause real damage. This calculator applies the exact conversion factors, 1 lb·ft equals 1.35582 N·m and 1 kgf·m equals 9.80665 N·m, so a torque spec from one manual converts precisely to whatever unit your torque wrench actually displays. Getting this conversion even slightly wrong when tightening something like a cylinder head or wheel bolt can mean a fastener that's dangerously loose or stripped from over-tightening, so precision here matters more than in many everyday unit conversions.
Worked example
100 N·m
Result: 73.76 lb·ft, 10.20 kgf·m
