Editing Metrication (section)

===Legacy of previous units===
*In Australia, pints are still used for beer, though a pint has been redefined to be 570 ml (see [[Australian beer#Beer glasses|Australian beer glasses]])).
*[[McDonald's]] sells ''[[Quarter Pounder]]s'' under their original name in all English-speaking countries despite metrication. In the Netherlands and Finland, it is known as a ''Quarter Pounder Cheese'' while Sweden also refers to it as ''QP Cheese''. In [[Quebec]], it is called a ''Quart de livre''. In Latin America and Spain, it is called ''Cuarto de Libra con Queso''. In Taiwan, it is known as the ''four-ounce beef burger''.
*Inch-based spare parts are occasionally kept to service American and pre-1950s machines, but screws are changed to [[metric thread]] at maintenance.
*In [[plumbing]], some pipes and pipe threads are still designated in inch sizes due to historic international acceptance of particular sequences of pipe sizes and pipe threads, such as [[British Standard Pipe|BSP/ISO 7/EN 10226]] threads.
