United States customary units are a system of measurements commonly used in the United States. The U.S. customary system developed from English units which were in use in the British Empire before American independence. Consequently most U.S. units are virtually identical to the British imperial units. However, the British system was overhauled in 1824, changing the definitions of some units used there, so several differences exist between the two systems.
The majority of U.S. customary units were redefined in terms of the meter and the kilogram with the Mendenhall Order of 1893, and in practice, for many years before. These definitions were refined by the international yard and pound agreement of 1959. The U.S. primarily uses customary units in its commercial activities, while science, medicine, government, and many sectors of industry use metric units. The SI metric system, or International System of Units is preferred for many uses by NIST
The system of imperial units or the imperial system (also known as British Imperial) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but some Imperial units are still used in the United Kingdom and Canada.
Brassiere measurement (also called brassiere size, bra size or bust size) refers to determining what size of bra a woman wears and mass-producing bras that will fit most women. Bra sizes usually consist of a number, indicating a band size around the woman's torso, and one or more letters indicating the breast cup size. Bra cup sizes were invented in 1932 and band sizes became popular in the 1940s.
Bra sizes vary from one manufacturer to another, and from country to country. Women's bodies and breasts may not conform to the sizes offered by companies. As a result, some women have a difficult time finding a properly fitted bra. Up to 80% of women wear the wrong size bra causing 40% to 60% to experience pain of one kind or another.]citation needed[ Environment
