Number of cells in an adult human body. Also, cell type composition in an adult human body (over the timescale of months but not years because aging).
Relative size of predator/​prey species population in a mature, mostly otherwise static ecosystem.
Warm-blooded mammal body temperature.
#1 in particular is definitely a useful frame to use in practice.
