180 degrees longitude

As it is, London is 51.5 degrees north of the Equator, which means it’s only 38.5 degrees from the North Pole. Hence it’s closer to the North Pole than it is the Equator. However, as you insist on doing it by distance, that makes London 5,722 km from the Equator and 4,278 km from the North Pole.

The total flight duration from United States to London, United Kingdom is 9 hours, 30 minutes. If you’re planning a trip, remember to add more time for the plane to taxi between the gate and the airport runway.

It’s exactly 10,000 km. This is because the definition of a meter is 1 10,000,000th of the distance from the North Pole to the equator. So it’s exactly 10,000,000 meters from the North Pole to the equator, which is exactly 10,000 km.

A degree of longitude is widest at the equator with a distance of 69.172 miles (111.321 kilometers). The distance gradually shrinks to zero as they meet at the poles. At 40 degrees north or south, the distance between a degree of longitude is 53 miles (85 kilometers).

The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on. In India, the standard meridian is 82-and-half degree.

Globes have horizontal and vertical lines that make up a coordinate grid system. The horizontal lines that cross the earth are the lines of latitude. The vertical lines that cross the earth are the lines of longitude. All lines of latitude measure either north or south from the 0-degree line of latitude (the equator).

The imaginary horizontal lines running in east-west direction on the Earth’s surface are known as Latitudes or parallels of Latitude as they are Parallel to each other.
