About this tool
Convert your dog’s age into human years with the modern epigenetic formula and the old 7× rule.
Epigenetic clock (Wang et al., 2020): human age ≈ 16 × ln(dog age) + 31. The traditional rule multiplies by 7.
Formula: human ≈ 16·ln(dog) + 31
Example: Dog’s age (years) = 1 → Human years (epigenetic) = 31, Human years (7× rule) = 7.
