About Giganewtons
One giganewton (GN) is 10⁹ N ≈ 100,000 metric tonnes-force - the scale of geophysically significant forces. Earth-Moon gravitational attraction is ~198 GN, driving tidal forces. The Himalayan collision zone transmits hundreds of GN per km of plate boundary. The Hoover Dam's structural dead load is ~67 GN. For comparison, the entire Saturn V launch thrust was only 33.4 MN = 0.033 GN, illustrating that giganewtons are truly planetary in scale. 1 GN = 1,000 MN = 10⁹ N = 224,800 kips.
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.
