Convert Gram-force millimetres to Newton millimetres
Convert Gram-force millimetres (gf·mm) to Newton millimetres (N·mm) instantly and accurately.
Conversion Formula
N·mm = gf·mm × 0.00980665
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 millimetres
The newton millimetre (N·mm) equals 10⁻³ N·m, widely used in mechanical engineering and FEA software. ANSYS, Abaqus, and Siemens NX models built in millimetres report torques in N·mm for dimensional consistency. Fastener torque for M3-M6 screws (typically 0.3-5 N·m range), micro-pump impeller loads, and precision gearbox calibration values are expressed in N·mm. 1 N·mm = 10⁻³ N·m = 0.1 N·cm ≈ 8.851 × 10⁻³ lbf·in.
