Imperial System

The imperial system is a system of weights and measures that was originally developed in England.  It uses length units:  inch, foot (12 inches), yard (36 inches), mile (5280 feet).  It uses weight units:  ounce, pound (16 ounces), ton (2000 pounds).  It uses volume units:  quart, gallon (4 quarts).  In most countries the metric system has replaced the imperial system since it is more logical and consistent mathematically.
