Assuming the pre-surgery length was something normal (making it a rounding error from this point on) and the average 3.5" long flaccid penis takes 130 mL of blood to achieve a 5.17" erection (4.59" in circumference), those extra ~2.1 billion inches would require 5.4 million-ish liters of blood to fill. If those are 2.1 billion flaccid inches, call it about 8 million liters.
Average total blood volume for an adult human is 4.5 to 5.6 liters so we’re going to need more. An Olympic swimming pool is 50x25 meters with a minimum depth of 2 meters. That’s 2.5 million liters. It’ll take two of those full of blood and a little extra to get things up and running.
Somewhere in that ballpark anyway, I think. Don’t rely on this for medical purposes. Average dick-mensions and pool specifications from Wikipedia, blood fill numbers from a Healthline article.
5.17 is the new average? I remember decades ago it was 6. It’s been slightly lowered every couple years. Science is making me feel better one update at a time
A lot of studies regarding penis length are self-reported. So basically subtract an inch from the results and you get a more accurate picture.
It’s also why countries that censor genitals in porn report smaller penises than countries where the race of the local population is heavily fetishized wrt. supposed “big dicks”. When actually measuring, all those differences become smaller than is statistically relevant.
