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 Cups
A cup = 8 fl oz = 16 tbsp ≈ 236.6 mL - the fundamental unit of American cooking. Almost every US recipe uses cups for dry and liquid ingredients. The US customary cup (236.588 mL) differs from the US legal cup (240 mL, used in nutrition labelling) and the metric cup (Australia/Canada: 250 mL). Kitchen sets come in 1/4, 1/3, 1/2, and 1 cup sizes. 2 cups = 1 US pint.
