WebJun 8, 2024 · Aristotle not only taught that Earth was spherical but also mentioned early estimates of Earth’s circumference. Mathematicians of his time had estimated Earth’s circumference to be “400,000 stadia”, or 62,880-66,680km (39,000-41,500 miles), depending on how stadia are converted to modern metric units. This value is about 20,000-25,000km ...
