The circumference of the Earth at the equator is commonly stated as being 25,000 miles. To convert this distance into kilometers and meters, we can use the standard conversion factor:
1 mile is approximately equal to 1.60934 kilometers.
To find the circumference in kilometers, we multiply the number of miles (25,000) by the conversion factor:
Circumference in kilometers = 25,000 miles × 1.60934 km/mile
This results in:
Circumference in kilometers ≈ 40,233.6 km
To convert kilometers into meters, we know that 1 kilometer is equivalent to 1,000 meters. Therefore:
Circumference in meters = 40,233.6 km × 1,000 m/km
This gives us:
Circumference in meters ≈ 40,233,600 m
In summary, the circumference of the Earth at the equator is approximately 40,233.6 kilometers or 40,233,600 meters.
