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.
About Gallons
A US gallon (gal) = 4 quarts = 128 fl oz ≈ 3.785 L. Gasoline, milk, water, paint, and pesticides are sold by the gallon in the US. About 20% smaller than the UK imperial gallon (4.546 L) - a critical difference when comparing fuel economy across the Atlantic. 1 US gal = 3.785 L = 4 qt = 128 fl oz.
