Conversion Formula

aN = TN × 1.000000000e+30

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 Attonewtons

An attonewton (aN) is 10⁻¹⁸ N - the force scale of individual photon recoil and quantum vacuum effects. The thermal noise floor of an AFM cantilever at room temperature is ~1-10 aN/√Hz. A 532 nm photon absorbed by a trapped ion imparts ~0.3 aN of recoil. Casimir forces between conducting surfaces 10-100 nm apart are 1-100 aN. NEMS resonators have demonstrated force sensitivity below 1 aN/√Hz, enabling single-molecule adsorption detection. Optomechanical cavities probe radiation pressure at the attonewton scale to test quantum measurement limits. 1 aN = 10⁻¹⁸ N.
