Geography
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.

Geography
Elevation Grade Calculator
Compute the steepness of a slope as a grade percentage, an angle in degrees, or a rise/run ratio given the horizontal distance and elevation gain. Used for roads, railroads, ramps, hiking trails, accessibility ramps, and any inclined surface.
