Convert Poundal feet to Gram-force centimetres
Convert Poundal feet (pdl·ft) to Gram-force centimetres (gf·cm) instantly and accurately.
Conversion Formula
gf·cm = pdl·ft × 429.7095348
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.
About Gram-force centimetres
The gram-force centimetre (gf·cm) equals 9.80665 × 10⁻⁵ N·m, the standard unit for small servo and hobby motor specifications. RC servo motor stall torques are quoted in gf·cm - a typical 9 g mini-servo delivers 1500-2000 gf·cm. Small stepper motors for 3D printers range 400-600 gf·cm; model train gearboxes around 200-800 gf·cm. 1 gf·cm = 9.80665 × 10⁻⁵ N·m = 10 gf·mm = 0.01 kgf·cm.
