Distance Between Coordinates Calculator

Compute the distance between two latitude/longitude points using Haversine (great-circle), Euclidean (flat-Earth approximation), or Manhattan (city-block) formulas. Returns kilometres on a spherical Earth model — accurate to within ~0.5% for most use cases.

Map Scale Calculator

Convert a distance measured on a paper or digital map to the corresponding real-world distance using the map's scale ratio. Supports common scales (1:25,000 to 1:500,000) and unit conversions between cm/in/mm on the map and km/mi/m in the real world.
