You want the circumference, not the diameter. That is about 24,900 miles. So your car has gone around the Earth about 10.5 times ... did you get postcards on your journey? ... lol

If you want to know how many times your car has been around the earth, you are not looking for the diamenter of the earth; you are looking for the circumference. The earth is eliiptical in shape, but almost a sphere. Therefore, the circumference is different, depending on where you are. The biggest circumference is the equator, which is about 25 000 miles (40 000 km).

The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers).
But, if you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km). This the earth is a tad wider (25 miles / 41 km) than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

Let us take the diameter as approximately 8000 miles and see. So the circumference is approximately 25000 miles and so you have gone round the earth: Approximately 10 and one half times

A handy way to remember the circumference is that it is about 10,000 kilometres from the pole to the equator.
That's how the size of the kilometre was originally chosen.
So it is 40,000 km around the earth approximately.

The Earth is about 7,926 miles (12,756 km) in diameter, difficult to measure as it isn't a perfect sphere.

It was 4 inches but it's now 1 inch, hence the expression; it's a small world. The world is shrinking all the time, but so are we, so we don't notice. Your nails don't grow. That's just your fingers and toes shrinking. Same with your hair. Barbers know this but won't tell anyone.

The radius at the equator is approx. 6378km, so the equatorial diameter is twice that. The polar radius is some 20km less, so you can work out the distance from north to south pole.

I know the circumference of the world is 22,000 odd miles. The coast of greenland is longer than the circumference of the world, and even longer than the coastline of Africa!
