Altitude converter — meters, feet, km & miles elevation
An altitude converter (also called an elevation converter) switches height above a reference — usually mean sea level — between meters (m), feet (ft), kilometers (km), and miles (mi). Aviation briefings, hiking apps, GIS layers, and geography textbooks mix units by region; this free tool gives instant altitude unit conversion locally in your browser.
The US and UK aviation communities often quote feet MSL (above mean sea level). Many countries, mountaineering references, and scientific datasets use meters. When a chart says runway elevation 1,234 ft and your GPS shows meters, or a summit is listed at 8,849 m and you think in feet, a single feet to meters altitude lookup saves arithmetic errors.
