For that reason, our estimate of Earth's circumference is a little small.)

He measured the Earth's circumference by reference to the position of the star Canopus.

Also, those mathematicians who try to calculate the size of the earth's circumference arrive at the figure 400,000 stades.

Hard to judge how far away it was, but at least several hundred klicks, several degrees of the Earth's circumference.

This book is the original source for the well-known story of how Eratosthenes measured the Earth's circumference.

To make a rough estimate, we can determine Earth's circumference by multiplying its diameter by pi (3.1416).

Over the years, scientists have redefined units like the meter (first based on the earth's circumference) and the second (conceived as a fraction of a day).

Vince Calder I do not recall the exact figures for the earth's circumference at the equator but this number seems a little low to me.

The Earth's circumference was first determined around 240 BC by Eratosthenes.

"Another look at Eratosthenes' and Posidonius' determinations of the Earth's circumference".

Eratosthenes calculated the earth's circumference with remarkable accuracy, and Hipparchus Founded scientific astronomy.

Determined Earth's circumference.

If you travel from the equator to the North Pole, you cover a quarter of the Earth's circumference and therefore pass over 90 degrees.

Both men's figures for the Earth's circumference were uncannily accurate, aided in each case by mutually compensating errors in measurement.

Revising the figures attributed to Posidonius, another Greek philosopher determined 18,000 miles as the Earth's circumference.
