Measured at the equator, the Earth has a circumference of 40,075.017 km or 24,901.461 miles. But measured from pole to pole, that is to say, along the meridian line, the Earth has a circumference of 40,007.86 km or 24,859.73 miles. read more

The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid. read more
