An airspeed indicator measures the aircraft's airspeed and displays it in what units typically?

Explanation:
In flight, airspeed is standardized in knots because aviation uses nautical miles for distance, so speed is expressed as nautical miles per hour. The airspeed indicator measures dynamic pressure and converts it to indicated airspeed, which is read on the instrument in knots (often labeled as KIAS). This keeps instruments, charts, and airspace operations consistent worldwide. The other units—meters per second, kilometers per hour, or miles per hour—are not the customary cockpit readouts for airspeed.
