About these units
Short background on the units used in this conversion.
Newton Meter (N·m)
The newton-meter is the SI unit of torque and also of energy when used as work — one newton applied over one meter.
Newton-meters specify bolt torque in automotive manuals and mechanical engineering worldwide.
