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.

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.
