If 8 billion humans displace 50 gallons each, thats 400 billion gallons. The volume of all oceans is about 1.5 billion cubic kilometers, which is 3.96258e20 gallons.
Eh, I got tired of trying to do that math, but thats a big frickin difference. I dont think the sea level rise would be measurable.
How did you arrive at that number? It’s an entire SI prefix away from the estimate I got in a sibling comment, so I assume one of us has something wrong.
Edit: oh I see your other comment with the working. I think you may have the density wrong; if a density of “1” is in kg/m³ it’s way off – the density of water and approximately-humans is usually given as 1 kg/Litre.
50gal is quite generous; average adult weight estimate tops out around 80kg and that doesn’t account for children. Divided by approximate human density 1010kg/m³ gives 0.08m³ or around 21gal. Multiplying that by 8 billion humans and dividing by the ocean surface area of around 361000000 km² gives approximately… 1.8μm of sea level rise.
Hey that gives rise to a new shower thought. If you blended all humans and spread them out evenly across the earth, how many atoms thick would the layer of human be?

Try metric, it is way easier. The change will be about 2mm, whatever that in elephant heights or whatever is.

Yep, you are right, with ‘density of 1’ I meant 1g/cm^2. Which is indeed off.
