Square footage of the Earth The surface area of the Earth is:

4 * pi * r^2

= 4 * pi * (6378.1 km)^2

= 511201962.3 square km

And, since there are 3280.839895 feet per km, there are 10763910.42 square feet per square km.

So, the square footage of the earth (assuming a spherical shape, not ellipsoidal) is:

511201962.3 * 10763910.42

= 5.502532127 x 10^15 square feet

That's approximately:

5,502,532,127,000,000 square feet

Which is read, "Five quadrillion, five hundred two trillion, five hundred thirty-two billion, one hundred twenty-seven million square feet".
