Does anyone know the diameter (in game, not lore size) of the Imperial City? I am trying to make it in minecraft...

Thanks

This page describes the ratio of game units to real world distance:

7 units to 10 cm. So if you or someone can find out how many "units" the Imperial City diameter is, you'll have your answer. The number of units might be available by using the Construction Set.

Thanks, I did exactly that and got 27700 centimeters in diameter roughly.
