What is the length of the Prime Meridian in degrees?

Answer 1

Every meridian of longitude is a semi-circle that joins the north and south poles.

So the length of each one is 1/2 of the earth's polar circumference, about 12,400 miles. (rounded)

Answer 2

The Prime Meridian is 0 degrees in length, as it serves as the starting point for measuring longitude coordinates on Earth. It runs from the North Pole to the South Pole, passing through Greenwich, London.

Answer 3

The prime meridian runs from the North pole of Earth to the South pole of Earth, half the polar curcumference of the Earth (which is 24,859.82 miles or 40,008 km)

Answer 4
