Convert Gram-force metres to Poundal feet
Convert Gram-force metres (gf·m) to Poundal feet (pdl·ft) instantly and accurately.
Conversion Formula
pdl·ft = gf·m × 0.2327153389
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 Poundal feet
The poundal foot (pdl·ft) equals ≈ 0.04214 N·m, the torque unit of the absolute foot-pound-second system, where force is in poundals (1 pdl = 1 lb·ft/s²) rather than pound-force. It appeared in pre-SI British and American engineering texts and NACA aerodynamic stability reports alongside slug inertia values. 1 pdl·ft = 0.45359237 × 0.3048² N·m ≈ 0.04214 N·m ≈ 0.3730 lbf·in.
