About Newton metres
The newton metre (N·m) is the SI coherent derived unit of torque and bending moment. Car engine torque is commonly quoted in N·m - a family hatchback delivers 150-250 N·m; a performance saloon 400-600 N·m. Fastener pre-load torques, EV traction-motor ratings, and structural connection bolt specifications are all given in N·m. 1 N·m = 100 N·cm = 1000 N·mm ≈ 0.7376 lbf·ft ≈ 8.851 lbf·in.
About Gram-force millimetres
The gram-force millimetre (gf·mm) equals 9.80665 × 10⁻⁶ N·m, the natural unit for precision micro-mechanisms. Swiss watchmaking datasheets list hairspring and balance-wheel detent torques in gf·mm; micro-servo holding torques, precision force gauge spring calibration, and miniature dental handpiece torque limits also fall in this range. A typical watch hairspring torque is 0.1-5 gf·mm. 1 gf·mm = 9.80665 × 10⁻⁶ N·m = 100 dyn·cm = 0.1 gf·cm.
