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 ...
United States customary units form a system of measurement units commonly used in the United States and most U.S. territories [1] since being standardized and adopted in 1832.

The values of these units are based on Jefferson's proposal of a foot that was equal in length to one-fifth of a second rod, one fourth of an inch shorter than the foot in use at the time, and approximately equal to 0.298461684 m. [5] For the mass units, the ounce as a base would equal the weight of a cubic inch of pure water at standard ...
