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 Teranewtons
One teranewton (TN) is 10¹² N - the force scale of plate tectonics and planetary dynamics. Mantle convection drags tectonic plates with 10¹³-10¹⁵ N per plate, putting the plate-driving slab-pull force (~10¹³ N) firmly in the TN range. Mid-ocean ridge lithosphere sustains several TN per km of spreading length in tension. The tidal force differential across Earth's diameter from the Sun is ~4 × 10¹⁷ N = 4 × 10⁵ TN. Proposed megastructures (space elevators, orbital rings) would also require teranewton-scale structural capacity. 1 TN = 1,000 GN = 10¹² N ≈ 10¹¹ kgf.
