Nautical Mile (UK)
The nautical mile (UK) is a unit of distance used primarily in maritime and aviation navigation in the United Kingdom. Traditionally, it was defined as 6,080 feet (about 1,853 meters), which is slightly longer than the modern international nautical mile of 1,852 meters. This UK definition was used before international standardization in 1929. Today, the international nautical mile is widely adopted, but the UK nautical mile historically played an important role in navigation and mapping.
Earth Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator. It represents the Earth's radius measured along the equatorial plane.
Its value is approximately 6,378.1 kilometers (about 3,963.2 miles).
The Earth is not a perfect sphere but an oblate spheroid, so the equatorial radius is slightly larger than the polar radius.
This radius is important for geodesy, satellite orbits, and mapping.
Key facts:
Equatorial radius ≈ 6,378.1 km
Larger than polar radius due to Earth's flattening at the poles
Used in Earth sciences, navigation, and space missions
Understanding the Earth's equatorial radius helps in accurate modeling of the planet’s shape and gravitational field.
