Pound
Formal: oz
The ounce is used in both the US Customary and British Imperial weight systems and has been in use since before the time of Elizabeth I (1533-1603). In 1588 Elizabeth I approved a statute that fixed the avoirdupois pound at 7,000 grains which is the current size - this change was the last major change in definition affecting the ounce.
The ounce was one of the main units used in recipes and is still in common use in the UK by cooks, despite the metric system being adopted in 1970 and the ounce ceasing to be a legal unit of measure (for economic, health, safety or administration) in the year 2000. Interestingly the health/safety aspect of this legislation should prevent the ounce being used in commercial kitchens as a measure for ingredients.
The ounce is in statutory use in the United States and is informally used in the United Kingdom and British Commonwealth countries, such as Australia, Cannada, Jamaica, New Zealand and South Africa.
