About Tuns
A tun = 4 hogsheads = 252 US gallons ≈ 953.9 L - the largest traditional wine cask and origin of the English word 'ton': a full tun of wine weighed ~1 long ton. English shipping law rated cargo capacity in 'tuns burden'. Scottish distilleries use 'tun rooms' for large vatting/blending vats. 1 tun = 252 US gal = 2 pipes = 4 hogsheads ≈ 953.9 L.
About Cubic Kilometers
A cubic kilometre (km³) = 10⁹ m³ = 10¹² L. Lake Baikal: 23,615 km³ (world's largest freshwater lake by volume). Amazon River discharge: ~6,600 km³/year. Earth's total freshwater: ~35,000,000 km³; oceans: ~1,335,000,000 km³. Glaciologists track polar ice-sheet losses in km³/year as a key climate metric. 1 km³ = 10⁹ m³.
