The World in my Hand

Did you know the world isn't a perfect sphere?  It bulges a bit at the equator.  As does my inflatable world - I wonder if they designed it that way, or if it's just an imperfection in the manufacturing process...?   Anyhow, the question is...

If my inflatable globe measures 26.65 cm from pole to pole (i.e. in a straight line, a.k.a. the diameter), then to what scale has my globe been manufactured?
