Geography Reference

Geographic Reference for Every Question About the World

Geographic reference questions come in many forms: which country is the largest by area? What are the coordinates of a specific city? How large is France compared to Texas? What is the magnetic declination at a given location? What is on the opposite side of Earth from where you are? These tools answer all of these questions with accurate, well-organized data.

World Country Reference: 195 Countries in One Database

The World Country Reference covers every recognized sovereign nation — all 195 UN member states plus Kosovo and Taiwan — with the following fields: official name and common name, capital city, continent and region, land area in square kilometers and square miles, population, currency name and code, country calling code, internet country code (TLD), driving side (left or right), and a geographic region classification. The database is fully sortable and searchable — sort by area to see Russia (17.1 million sq km) at the top and Vatican City (0.44 sq km) at the bottom, or search by currency to find all countries that use the Euro.

Country Area Comparison adds a visual dimension — select two countries and see a proportional area comparison. This is useful for building intuitive geographic scale: Texas (695,662 sq km) is larger than France (551,695 sq km). The entire contiguous United States (7.65 million sq km) is slightly smaller than China (9.6 million sq km). Alaska alone (1.72 million sq km) is bigger than Texas, California, and Montana combined. These comparisons are hard to internalize from numbers alone.

Coordinates and Location Lookup

The Latitude/Longitude Finder takes a place name — city, landmark, address, or geographic feature — and returns its decimal degree coordinates. This is useful when you have a destination's name but need its GPS coordinates to enter into a calculator or navigation device. Coordinates are returned as decimal degrees (DD) format; use the Coordinate Converter in the Coordinate and Distance cluster to translate to DMS or UTM if needed.

Magnetic Declination: Essential for Accurate Compass Navigation

A magnetic compass doesn't point to true north — it points to the Earth's magnetic north pole, which currently sits in the Canadian Arctic near Ellesmere Island, about 500 kilometers from the geographic North Pole. The difference between where a compass points and true north is called magnetic declination, and it varies significantly by location. In Maine, declination is about 16° West — a magnetic bearing of 0° actually points 16° west of true north. In parts of Alaska, declination reaches 20° East. In the eastern Midwest, declination is close to 0°. The Magnetic Declination Lookup tool returns the current declination value for any coordinates, sourced from the World Magnetic Model. For serious navigation — especially off-trail hiking, orienteering, or maritime navigation — applying the correct declination is essential for accurate compass bearings.

Antipodes, Nautical Miles, and the Speed of Light

The Antipode Finder shows the point on Earth's surface directly opposite any location — the place you'd emerge if you dug straight through the center of the Earth. Most of the US is antipodal to the southern Indian Ocean. Parts of Argentina and Chile are antipodal to China and Southeast Asia. New Zealand's North Island is roughly antipodal to Spain. The tool returns the antipode coordinates and the nearest named land feature or ocean. The Nautical Mile Converter handles the unit common in maritime and aviation navigation — 1 nautical mile equals exactly 1,852 meters or 1.15078 statute miles, and corresponds to one arc-minute of latitude (1/60th of a degree). The Speed of Light Distance Calculator answers the kind of astronomical scale questions that come up in science: light travels 299,792 km in one second, covering the 384,400 km Earth-Moon distance in about 1.3 seconds and the 150 million km Earth-Sun distance in about 8 minutes 20 seconds.
