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 Long Ton-Force
One long ton-force is the gravitational force on an imperial long ton (2,240 lb = 20 × 112 lb hundredweight) - approximately 9,964 N. The long ton was the traditional British ton; long ton-force appears in Royal Navy vessel displacement records, British Admiralty anchor chain standards, pre-metrication UK bridge live load codes, and Australian/South African mining bolt pull-out specifications. It sits between short ton-force (8,896 N) and metric tonne-force (9,807 N) - about 12% heavier than a short ton-force. 1 long tf = 2,240 lbf = 9,964.02 N.
