How many millimetres is it around the earth?

Answer 1

The equatorial diameter is about 40,076 kilometers.

The polar diameter is about 40,008 kilometers.

Converting these to millimeters multiplies these figures by a factor of one million.

So, through the middle, top to bottom is 40,008,000,000 millimeters (4.0008 x 1010 mm).

Through the middle, side to side, is 40,076,000,000 millimeters (4.0076 x 1010 mm).
