It's been 230 years since British pirates robbed the US of the metric system

Queen Anne gallon

The US pint, gallon, FL Oz etc are actually derived from the old English queen Anne gallon, the standard used in the UK when the Americas were colonies. A queen Anne gallon (US Gallon) was defined by 8lbs of wine as oppose to 10lb of water at 60F in the imperial gallon. Since the density of wine and water are marginally different this of course alters the volume of the fluid ounce. In 1820 Britain modernized and redefined the imperial gallon but America kept into the old English standard.
