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.

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.
