>>8212293Human cells vary a bit in size from between 1– 100µm in diameter. A blood cell is about 10µm in diameter and represent a decent common middle ground.
A person is in the general range of about 2 meters tall, 0.5 meters wide, and 0.25 meters thick. So they occupy around 0.125 m^2 (= 0.125 x 10^6 10µm^2) of ground space standing up, and about 1 m^2 (=1 x 10^6 10µm^2) when lying down.
I’mma use Chicago to represent a city. Chicago is around 606.1 km^2 = 606.1 x 10^6 m^2.
So if a cell is equivalent to a person lying down, a person lying down takes up in the order of 1/6000th of a cities worth of area.
You can probably shave off a few of orders of magnitude of difference there if you go by volume instead, since a city is extremely thin and spread out, while a person’s dimensions are more like 1:2:4 in ratio, most of which they actually take up.
