The British Imperial System, also known as the Imperial Units or the Imperial System, is a measurement system that was used by the United Kingdom and its colonies. It consists of units such as pounds, ounces, gallons, and yards. In other parts of the world, this system is often referred to as the Imperial measurements. However, some alternatives to this term include the British Standard Units, the Imperial Standard Units, and even the Colonial System. While this system is no longer commonly used in the UK, it is still used in some countries, particularly those that were once under British rule.
