Convert Gram-force millimetres to Newton centimetres
Convert Gram-force millimetres (gf·mm) to Newton centimetres (N·cm) instantly and accurately.
Conversion Formula
N·cm = gf·mm × 0.000980665
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 Newton centimetres
The newton centimetre (N·cm) equals 0.01 N·m, a convenient unit for small-to-medium motors and robotics. Hobbyist robot joint actuators, prosthetic hand finger joints, and compact CubeSat reaction wheels are rated in N·cm. RC drone racing motors and small AC induction motors up to 100 W produce 5-200 N·cm. 1 N·cm = 0.01 N·m = 10 N·mm ≈ 1.416 ozf·in ≈ 0.0885 lbf·in.
