Distance Between Coordinates Calculator vs Map Scale Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
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.
- Answers
- Distance (km)
- Inputs
- Starting Latitude, Starting Longitude, Destination Latitude, Destination Longitude, Calculation Method
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.
- Answers
- Real Distance
- Inputs
- Distance on Map, Map Measurement Unit, Map Scale (1:X), Real Distance Unit
