What Is a Length Unit?
A length unit is a measurement used to express distance or size. Different systems exist around the world — the metric system (millimeters/millimetres, centimeters/centimetres, meters/metres) is standard in most countries, while imperial units like inches and feet are still widely used in the United States and the UK.
