# Definition of Imperial System

The Imperial system is a system of weights and measures that was originally invented in England, and officially used in Australia until 1970. A slight variation on this system is still used in the United States, for example, but the metric system has officially replaced the Imperial System in most countries, including England.

The following are some examples of Imperial Units of Measurement:

• Volume: fluid ounces, quarts, pints, gallons
• Weight: ounces, pounds, stone, tons
• Length: inches, feet, yards, miles
• Area: square inches, square feet, square yards, acres

It is possible that your grandparents are more familiar with the Imperial System of measurement and still talk about feet, inches, pounds and so on.
