Real use case

Screen sizes, monitor arms, IKEA mismeasurement

Screen sizes are always in inches globally — a 27-inch monitor is 68.6 cm diagonal, a 15.6-inch laptop is 39.6 cm. Human height is a big search driver: 165 cm ≈ 5'5", 170 cm ≈ 5'7", 180 cm ≈ 5'11". Monitor arms and desk-mounting hardware label in one system while the desk is measured in the other; furniture assembly instructions from IKEA are metric but tape measures in North American homes are usually imperial-first.

Length conversions in context

Where length conversions actually come up

Length conversions are the day-to-day currency of anyone crossing the metric/imperial divide — international students converting a US-labelled apartment description ("400 sq ft" — is that a studio?), runners comparing their 5K to a 3.1-mile route, ergonomics setups that came with cm-only specs, or IKEA-style flat-pack instructions measured in mm when your tape only has inches. The math is trivial (1 inch = 2.54 cm, exactly, by international agreement since 1959); the value of a converter is not doing that math in your head at 11 pm.
