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.

About Millinewtons

A millinewton (mN) is 10⁻³ N - the force scale of lightweight structures and precision connectors. A mosquito weighs ~1-3 mN; a grain of rice ~29 mN; a paper clip ~40 mN. USB connector insertion forces are specified at 40-80 mN; keyboard switch actuation (ISO 9241) 40-80 mN. Piezoelectric hard drive head positioning actuators deliver 10-100 mN. Spider dragline silk (4 µm diameter) breaks at 40-60 mN - among the highest specific strengths in nature. Flexible electronics peel-force and thin-film adhesion tests also operate in the mN range. 1 mN = 10⁻³ N.
