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 Femtonewtons
A femtonewton (fN) is 10⁻¹⁵ N - the force scale of single-molecule biology. RNA polymerase exerts a stall force of ~14-25 fN while transiting DNA at 10-50 bp/s. Myosin V motor proteins step 37 nm with ~1-3 fN per head. The viscous drag on a 100 nm nanoparticle moving at 1 µm/s through cytoplasm is ~0.2-0.5 fN. Optical tweezers with back-focal-plane detection resolve sub-femtonewton forces, enabling measurement of single-enzyme output. AFM receptor-ligand unbinding (e.g., biotin-streptavidin) gives adhesion forces of 100-300 fN. 1 fN = 10⁻¹⁵ N.
