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.
About Dyne centimetres
The dyne centimetre (dyn·cm) is the CGS unit of torque, equal to 10⁻⁷ N·m. It represents 1 dyne of force applied at 1 cm from the axis. MEMS micro-actuator friction, watch escapement detent torques, and laboratory torsion-pendulum experiments are measured in dyn·cm. Pre-SI physics literature and precision galvanometer calibration reports used this unit. 1 dyn·cm = 10⁻⁷ N·m = 0.01 gf·mm = 0.001 gf·cm.
