About Acre-Feet
An acre-foot (ac ft) = the volume covering 1 acre to 1 ft depth ≈ 1,233.5 m³ (325,851 US gal). Almost exclusively used in US water resource management. California's Lake Shasta: 4.55 million ac ft at capacity. A typical US household uses ~0.5-1 ac ft/year. Water rights on the Colorado and Sacramento rivers are traded in acre-feet. 1 ac ft ≈ 1,233.5 m³.
About Cubic Inches
A cubic inch (in³) is the volume of a cube with sides of one inch (25.4 mm), equal to approximately 16.387 mL. It is widely used in US engineering and manufacturing - engine displacement was traditionally described in cubic inches (a 350 in³ V8 engine displaces 5.7 liters), and product specifications for items sold in the US frequently reference cubic inches. Speaker cabinet volumes, wine bottle capacities in older US standards, refrigerator compartment sizes, and box shipping calculations in imperial units all use cubic inches. One liter equals approximately 61.024 cubic inches.
