I did a little arithmetic, at 1.16 dollars per euro and 11.11 sqft per sqm, and reulted in 1228 eur/sqm in the US, compared with 2-3000 eur/sqm in Germany.
So half or a third the cost. That is significant.
[Edited: I see others have had the same idea to regularize the units, now we can check each other's work ;)].
