Geography Calculators
Geographical and earth science calculations
Atmospheric Pressure Calculator
Calculate atmospheric pressure at different altitudes using barometric formulas. Essential for aviation, meteorology, and altitude-related scientific applications.
Bearing Calculator
Calculate bearings and directions between geographic points. Supports true, magnetic, and grid bearings for navigation, surveying, and outdoor activities.
Coordinate Converter
Convert between coordinate systems including latitude/longitude, UTM, MGRS, and state plane. Supports multiple geodetic datums for precise geographic positioning.
Distance Calculator
Calculate distances between geographic coordinates using Haversine, Vincenty, and other geodetic formulas. Essential for navigation, travel planning, and mapping.
Elevation & Slope Calculator
Calculate elevation changes, slope gradients, and topographic metrics for terrain analysis. Essential for hiking, construction planning, and geographic studies.
Geographic Area Calculator
Calculate areas of geographic regions using coordinate-based methods. Determine land area for properties, countries, and natural features with different projections.
Humidity Index Calculator
Calculate heat index, relative humidity, and thermal comfort metrics. Determines perceived temperature in hot conditions and evaluates weather-related health risks.
Population Density Calculator
Calculate population density for geographic areas using population and area data. Analyze demographic patterns and compare regional population distributions.
Sunrise & Sunset Time Calculator
Calculate sunrise and sunset times based on location and date
Temperature Converter
Convert temperatures between Celsius, Fahrenheit, and Kelvin scales. Includes absolute zero calculations and relative temperature change conversions for science.
Wind Chill Calculator
Calculate perceived temperature based on air temperature and wind speed. Determines frostbite risk and necessary precautions for cold weather conditions.
