The "effective volume" of the Earth's atmosphere is about 4.2 billion cubic kilometers. This figure is the surface area of the Earth (509 million square kilometers) times the "effective thickness" of the atmosphere (8.2 kilometers, or about 27,000 ft). The effective thickness and volume are what the thickness and volume of the atmosphere would be if the entire atmosphere were at sea level conditions.

The actual volume of the atmosphere is considerably greater than its effective volume, as its pressure and density drop with increasing altitude. If we adopt the "Karman Limit" of 100 km elevation as the boundary between earth and space, the volume of the atmosphere would be 100 times 509 million or about 51 billion cubic kilometers. However, the Karman Limit is a non-physical and rather arbitrary boundary.

Earth isn't in the atmosphere - the atmosphere is part of Earth.

First we'll need to go with the flow and assume the atmosphere extends about 621 miles above the earths surface. At the equator the earth has a diameter of about 7,926.41 miles; this makes the spherical diameter of the enclosed sphere 7,926.41 mi. + (2 * 621 mi.) = 9,168.41 miles. Diameter / 2 = radius so that gives us 4584.205 miles. Volume of a sphere is 4/3 * (pi * r^3) so the volume of our sphere so far is 403,534,528,218.6 miles; this is including the volume of the earth. To figure the volume of the atmosphere we subtract the volume of the earth which is 4/3 * pi * 3963.205^3 = 260,752,343,761.16 miles. So, volume in cubic miles of the earths atmosphere is 142,782,184,457.44 depending on whose number you go with for the 'thickness' of the atmosphere.
