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.

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.
