A corncrake aged 3 years is like a human aged 75 years

How old is a corncrake aged 3 years in human years?
About 75 years (accuracy ±11 months 2 weeks).
Why is the age not converted linearly?
Species age unevenly: childhood, maturity and old age take a different share of life, so the calculator matches the life stages of both species.
Can I choose another age or species?
Yes, the page has the calculator: pick the species, sex and age, and the result is recalculated.
