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 Long Ton-Force
One long ton-force is the gravitational force on an imperial long ton (2,240 lb = 20 × 112 lb hundredweight) - approximately 9,964 N. The long ton was the traditional British ton; long ton-force appears in Royal Navy vessel displacement records, British Admiralty anchor chain standards, pre-metrication UK bridge live load codes, and Australian/South African mining bolt pull-out specifications. It sits between short ton-force (8,896 N) and metric tonne-force (9,807 N) - about 12% heavier than a short ton-force. 1 long tf = 2,240 lbf = 9,964.02 N.
