Conversion Formula
TN = nN × 1.000000000e-21
About Nanonewtons
A nanonewton (nN) is 10⁻⁹ N - the force scale of AFM, MEMS, and nanoscale adhesion. AFM contact-mode tip-sample forces are held to 1-100 nN to image surfaces without damage. A single gecko seta generates ~200 nN of adhesion via van der Waals forces; one million setae per foot give ~10 N total grip. Smartphone MEMS accelerometers sense nanonewton inertial forces from proof-mass displacements. Carbon nanotubes fracture at forces in the nanonanonewton range per tube. CubeSat cold-gas microthrusters produce single-digit nN thrust for attitude control. 1 nN = 10⁻⁹ N.
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.
