It's close to 40,000 km, because the inventors of the metric system wanted the meter to be related to the distance from the equator to the pole via Paris. They figured 1/10,000,000 of that distance would be a useful unit of measurement, making it exactly 10,000 km from the equator to the pole, for a total circumference of 40,000 km.
Later measurements refined the figure, but it's still fairly close. It's different around the poles and around the equator.
