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 Cubic Feet
A cubic foot (ft³) is the volume of a cube with sides of one foot (30.48 cm), equal to approximately 28.317 liters. It is widely used in US construction, HVAC engineering, natural gas distribution, and real estate. Natural gas consumption is billed in cubic feet (Ccf = 100 ft³, Mcf = 1,000 ft³); refrigerator, oven, and storage compartment capacity are rated in cubic feet; and concrete or soil orders are quoted in cubic yards or cubic feet. One cubic foot of water weighs approximately 62.4 pounds. Air conditioning units are sized in BTU per hour for room volumes measured in cubic feet.
