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.
About Cubic Miles
A cubic mile (mi³) ≈ 4.168 km³ = 4.168 × 10¹² L. Lake Superior: ~2,900 mi³ (world's largest freshwater lake by surface area). Total volume of all glaciers and ice caps (excl. Antarctica and Greenland): ~170,000 mi³. Volcanic magma chamber sizes and major US aquifer volumes are sometimes quoted in cubic miles in American geoscience literature. 1 mi³ ≈ 4.168 km³.
