Altitude Altimeter (ft)

Altitude Altimeter (ft) is a free Chrome extension providing a simple, large-font altimeter display that shows your current ground surface height above sea level in feet. Using GPS measurements, it presents your elevation alongside a map of your position for easy reference. The extension also features a handy conversion calculator to switch values between feet (ft) and meters (m), aiding users who need metric or imperial units.

Designed to help prevent flooding and distress by keeping users informed about their elevation, this tool emphasizes clarity and simplicity. Note that GPS-based altitude measurements may have some errors due to signal variability, but it remains a practical and accessible option for quick elevation insights.
