Põhjalaiuskraadi

Põhjalaiuskraadi, commonly translated as northern latitude, refers to the angular distance, measured in degrees, north of the Earth's equator. It is a fundamental concept in geography and navigation, used to pinpoint locations on the planet's surface. Values for northern latitude range from 0 degrees at the equator to 90 degrees at the North Pole. The Earth is divided into two hemispheres by the equator: the Northern Hemisphere and the Southern Hemisphere. Põhjalaiuskraadi specifically denotes locations within the Northern Hemisphere. Lines of latitude, also known as parallels, are imaginary circles drawn around the Earth parallel to the equator. Each degree of latitude is approximately 111 kilometers or 69 miles. Therefore, a location at 30 degrees põhjalaiuskraadi is approximately 3,330 kilometers north of the equator. Understanding põhjalaiuskraadi is crucial for mapmaking, determining climate zones, and setting celestial navigation. It forms one of the two essential components, along with longitude, for defining any point on Earth.
