I looked into it once before, the short answer is because the letter predates the distinction between “u” and “v”.
Edit: Here’s a comment I made a while ago on the same topic with a little more information: https://lemmy.world/comment/10659648
I also did some napkin math on it and got a very different number. I don’t have the game so I saw people reporting the game is 150GB on PC. CDs can store up to 700MB of data, so (150 x 1024) / 700 ≈ 219.4 but we can round that up to 220. The standard CD is 1.2mm in thickness, so 220 x 1.2mm = 264mm which is a quarter of a meter.
I’m curious how my result differed from yours.
