Look at that hole in a fairly recent (2000 year old?) human skull.
How many centimeters in size do you think it is?
There’s a scale bar right next to the hole, and that scale is in millimeters, and it looks like it’s more than 1 centimeter (or 10 millimeters) and less than 2 centimeters (or 20 millimeters).
If you guessed 1.7 centimeters, or 17 millimeters, you are correct, because that’s what the Ministry of Antiquities, located in Cairo, said was the measurement on their Facebook page.
قطر يبلغ حوالي 1.7سم
But when they translated their statement into English, they accidentally translated 1.7 cm as 17 cm.

Oh well!
