60 megatons. Study mentions that the 12 megatons of ants are equivalent to 20% of the total human mass.

About 500 megatons. 7e9 humans * 0.075 tons/human / 1e6 tons/megaton

No, 600 megatons (~E12 kg) is closer. There are E10 humans and we weigh E2 kg. More precisely: 6E1 kg * 8E9 = 5.6E11

Numbers are to be considered about dehydrated mass, again according to the study.

Interesting. I didn’t read the study. I wonder if that favors smaller animals? Are large mammals a larger fraction water?
