It equals 3 US liquid quarts or 0.75 US gallons (2.8 L; 0.62 imp gal), [1] [2] [3] although some sources state that a trade gallon equals 2.7 litres (0.71 US gal). [4] Notably, 10 trade gallons equals 30 US quarts, which in turn equals 1.0 cubic foot, a common unit of measurement for soil.
Milk is usually sold in half-pints (8 fluid ounces), pints, quarts, half gallons, and gallons. Water volume for sinks, bathtubs, ponds, swimming pools, etc., is usually stated in gallons or cubic feet. Quantities of gases are usually given in cubic feet (at one atmosphere). Minims, drams, gill, and pottle are rarely used currently.
The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
The US Customary system of units makes use of set of dry units of capacity that have a similar set of names [Note 7] to those of liquid capacity, though different volumes: the dry pint having a volume of 33.6 cubic inches (550 ml) against the US fluid pint's volume of 28.875 cubic inches (473 ml) and the imperial pint of 34.68 cubic inches (568 ...
Volume may be measured either in terms of units of cubic length or with specific volume units.

In the U.S., particulate emission levels, used to monitor and regulate pollution, are sometimes measured in grains per cubic foot instead of the more usual ppm by volume. [23] [24] This is the same unit commonly used to measure the amount of moisture in the air, also known as the absolute humidity. [25]
