Timekeeping: Longitudes are the basis for time zones. Each 15 degrees of longitude corresponds to one hour of time difference. This allows us to coordinate time globally.

 

Navigation: Longitudes help sailors and pilots determine their east-west position, aiding in accurate navigation.

 

Geographic Coordinates: Longitudes, combined with latitudes, provide precise geographic coordinates for any point on Earth.
