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 Metric Ton-Force
One metric tonne-force (tf) is the gravitational force on 1,000 kg under standard gravity - exactly 9,806.65 N = 9.80665 kN. It dominates international heavy engineering: crane hook capacities are rated in tf (a '50-tonne crane' lifts 50 tf = 490.3 kN); ship mooring lines, anchor holding power, and cargo lashing per IMO standards are in tf; hydraulic presses for metal extrusion and stamping in Europe and Asia are rated in tf. ISO 7531 lifting-gear working load limits (WLL) use tf. 1 tf = 1,000 kgf = 9,806.65 N = 2,204.6 lbf.
