The cubic inch and the cubic foot are used as units of volume in the United States, although the common SI units of volume, the liter, milliliter, and cubic meter, are also used, especially in manufacturing and high technology. One cubic inch is approximately 16.387 mL.
One cubic foot is equal to exactly 1,728 cubic inches (28.32 L) because 123 = 1,728.[citation needed]
