Where Inches and Centimeters are used
The metric system (millimeters, centimeters, meters, kilometers) is used almost everywhere, while the United States, and partly the UK, still use inches, feet, yards and miles for everyday lengths. Product listings, construction plans and sports often mix both, which is why conversions are needed so often.
