Altitude converter — meters, feet, km & miles elevation
Altitude and elevation describe height above a reference — usually mean sea level. Aviation briefings, hiking apps, GIS layers, and geography textbooks mix meters and feet by region. This converter switches between m, ft, km, and mi for vertical distance from one input.
US and UK aviation often quote feet MSL; many countries and scientific datasets use meters. When a chart lists runway elevation 1,234 ft and your GPS shows meters, or Everest is 8,849 m and you think in feet, a single conversion avoids arithmetic errors.
