Converting length usually comes up when working with foreign data: height and dimensions in inches and feet, distances in miles, screen diagonals in inches, or specs for gadgets and furniture from the US and UK. A few handy reference points: 1 inch = 2.54 cm, 1 foot = 30.48 cm, 1 yard = 0.9144 m, 1 mile ≈ 1.609 km.

Calculations go through the meter as a neutral base unit, so any pair of units converts precisely. Everything runs right in your browser, instantly, with no data sent to a server.
