Reply to comment by DaemonRai in TIL: The formal name for the Imperial system's measurements of weight (pounds/ounces) is the Avoirdupois system by NPC8705

No, they are not. The US uses US customary units (technically, it doesn't have a name - the code simply specifies it as "traditional systems of weights and measures".

There are significant differences between British Imperial and USC.

Avoirdupois is a system of measuring weight based on the fact that sixteen ounces are in a pound. The metric system is based on grams, and the avoirdupois system is based on pounds. - That's freedom units they're talking about.

And from the Avoirdupois System Wikipedia page - In 1959, by international agreement, the definitions of the pound and ounce became standardized in countries which use the pound as a unit of mass. The International Avoirdupois Pound was then created. It is the everyday system of weights used in the United States. It is still used, in varying degrees, in everyday life in the United Kingdom, Canada, New Zealand, Australia, and some other former British colonies, despite their official adoption of the metric system.

And those freedom units are a part of the USCS.

And the US doesn't use Imperial still. Imperial was only used in the Empire and Commonwealth.
