Geography
Population Density Calculator
Compute population density — people per unit area — from total population and area. The single most common metric for comparing how crowded different cities, countries, or regions are; used in urban planning, public health, and infrastructure capacity studies.

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.
