About Milligram-Force

One milligram-force (mgf) is the gravitational force on 1 mg under standard gravity - exactly 9.80665 × 10⁻⁶ N. It is the natural unit for ultra-precise analytical balances: a 0.001 mg readability balance resolves ~9.8 nN = 0.001 mgf. MEMS force sensors in precision weighing cells are specified in mgf. Watchmaking uses mgf gauges to measure hairspring and detent actuation forces. Entomology and microbiology measure insect and microorganism attachment forces in mgf. Aerospace composite strain sensors are calibrated with mgf reference weights. 1 mgf = 9.80665 µN = 0.980665 dyn.

About Poundal

The poundal (pdl) is the force unit of the foot-pound-second absolute system - the force to accelerate 1 pound at 1 ft/s² - approximately 0.1383 N. Introduced in 1877 by Thomson and Tait as the FPS analogue of the CGS dyne (1 dyn = 1 g·cm/s²; 1 pdl = 1 lb·ft/s²). The poundal is distinct from pound-force: since standard gravity = 32.174 ft/s², 1 lbf = 32.174 pdl. It survives in older British engineering texts and early 20th-century thermodynamics literature, but is otherwise obsolete. 1 pdl = 0.138254954376 N = 1/32.174 lbf.
