Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

The volume of Earth is 1,083,206,246,123,080,894,852 m3, or around 1.0832Ã—1021 m3, in scientific notation.

Calculation

Earth is an oblate spheroid, resembling a sphere flattened at the poles.

The volume of an oblate spheroid is

V = \frac{4}{3}\pi a^2 b

where π is the mathematical constant pi, and a and b are the equatorial and polar radii.

Substituting a = 6,378,135 m and b = 6,356,750 m, we get the above Earth volume.
