... that I can apply to comparing strength relations between different animals of drastically different sizes?
Example- Let's say a human was scaled down to the size of a rhinoceros beetle, which, in some species, are said to be able to lift 800-850 times their own weight for a 60 gram male specimen (some growing as large as 85 grams, or in exceptional cases, 120 grams). How much stronger would a rhinoceros beetle (or a human) be at either one's size?
If my calculations are correct, a 60 gram rhinoceros beetle can still lift more pounds of pressure on its back than some humans can. Anywhere from 48,000- 51,000 grams, or 106- 112.5lbs.
[b]Note that I'm not talking about a human lifting as much weight, proportionally, to a rhinoceros beetle at his/ her current size- that would equal to roughly 1- 2 M1 Abrams tanks. I'm talking about how strong a human would be at the size of a rhinoceros beetle.[/b]
[b]P.S.-[/b] Let's ignore the fact that arthropods, in general, require highly oxygenated atmospheres to grow to drastically larger sizes or how humans could never exist at a size of 60 grams.

I don't know of any equation but I will say that strength is inversely proportional to mass. The smaller the organism the higher its strength to body mass ratio. So a 60g beetle could not lift more than a human.
