The Turkish system of weights and measures was metricated in 1931. In the 20th century, the Winchester Quart was metricated to two and a half litres. Many other sectors metricated their operations in the late 1960s or early 1970s. In metricated areas, the equivalent is the kilometric point. At this time 45% of British exports were to metricated countries. Similarly, gasoline is sold by the gallon in many countries that are considered metricated.
