Roughly 6.56 feet per cell
You’ve probably heard somewhere that our gastrointestinal tracts measure up to 25 feet long. That’s pretty weird, considering many of us don’t grow to be over 5-foot-9. But if you take a look at the human body at the cellular level, you’ll find something even weirder.
Each cell in our bodies contains around 6 picograms of DNA, which is 6 x 10-12 grams. As you can see, it’s incredibly lightweight, but if you were to stretch the DNA out to its max length without it snapping, it would measure up to 6.56 feet long! Multiply that by however many cells there are in your body and you’ve got enough DNA to go to the moon and back about 66 times!
