Length is the most everyday kind of measurement — heights, distances, screen sizes, fabric, furniture. This category covers the full metric range from nanometers to kilometers alongside imperial and US customary units like inches, feet, yards and miles, plus nautical miles for navigation. All conversions use the exact international definitions, so 1 inch is precisely 2.54 cm and 1 mile is precisely 1.609344 km.
