Convert Gram-force metres to Newton millimetres
Convert Gram-force metres (gf·m) to Newton millimetres (N·mm) instantly and accurately.
Conversion Formula
N·mm = gf·m × 9.80665
About Gram-force metres
The gram-force metre (gf·m) equals 9.80665 × 10⁻³ N·m, used in scientific torsion and balance instrument calibration. Analytical balance torsion spring constants, laser-gyroscope gimbal friction torques, and lightweight UAV propeller starting torques are expressed in gf·m. It bridges gf·cm and N·m in laboratory-scale rotating experiments. 1 gf·m = 9.80665 × 10⁻³ N·m = 100 gf·cm = 0.001 kgf·m.
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.
