A Distance Calculator is a tool used to determine the distance between two points on a map or in a coordinate system. It can be useful for various purposes, such as planning travel routes, estimating travel time, or measuring distances for geographical studies. Users typically input the locations, which can be specified by addresses, coordinates, or landmarks. These calculators often utilize the Haversine formula or other mathematical methods to provide accurate results. Many online platforms and mobile applications offer distance calculation features, making it easy for anyone to find distances between cities, countries, or specific locations like restaurants and parks.
