The units
- N·m (newton metres): The SI unit of torque; standard for engines, motors and fastener specs.
- N·mm (newton millimetres): Small fasteners and precision instruments.
- N·cm (newton centimetres): Small motors and servo specs.
- kN·m (kilonewton metres): Structural moments and large drive shafts.
- lbf·ft (pound-force feet): US customary torque for engines, wheels and bolts (also written ft·lb).
- lbf·in (pound-force inches): Small US fasteners and electronics; 12 lbf·in = 1 lbf·ft.
- ozf·in (ounce-force inches): Small motors and servos in US datasheets.
- kgf·m (kilogram-force metres): Older metric torque specs, still common on Japanese equipment.
- kgf·cm (kilogram-force centimetres): Small motors and torque screwdrivers.
Torque is force times lever arm, so lbf·ft and N·m differ only by unit systems; ft·lb and lb·ft are the same torque, and neither is the energy unit foot-pound. Fastener torque specs assume the stated lubrication condition.
