The Vatican contains 4.54 living Popes per square kilometer, or .0454 Popes per hectare, or 11.76 Popes per square mile, or 0.018 Popes per acre, or 2 Popes per Acre. To include non-living Popes, multiply by anywhere from 69.5 to 70.5: 315.53-320.07 per square kilometer, or 3.155-3.2 per hectare, or 817.32-829.08 per square mile, or 1.251-1.269 per acre, or 139-141 per Acre.

Bonus useless fact: The membership of useless_facts is closed, and the owner/maintainer hasn't posted since 2010. And yet, it's still a community that regularly gets new and informative (if useless) posts.
