The circumference of Earth is the distance around it. Where can it be measured?

In fact, the circumference of the Earth is different whether you measure it at the poles or the equator due to the ellipsoid shape of the planet. Since ancient times, the circumference of the Earth has been a crucial factor in navigation. Eratosthenes performed the earliest known scientific measurement and calculation, achieving a high degree of accuracy in his calculation. Earth's circumference is measured both around the equator and around the poles.
