How much cells do we have in our body?

There are roughly trillions of cells in our body

Unfortunately this is a complicated question with no clear answer. It is impossible to count every individual cell, or even get a very close estimate. However based upon weight, volume, and a variety of other factors there is believed to be perhaps some 30 Trillion cells. This however is according to what I have learned, and what many other have learned and interpreted. Who knows there could be Quadrillions or Trillions.
