Metric and imperial length
Length is measured in metres in the metric system and feet, yards, and miles in the imperial system. Converting between them is just a matter of fixed ratios — one inch is exactly 2.54 centimetres, and one mile is 1,609.344 metres. This converter handles all the common units, including nautical miles for marine and aviation use.
