Bear → Human Age Conversion Rules
Bears mature quickly in their first year and then age more steadily in adulthood. This calculator uses wildlife biology estimates.
Conversion Formula
- For bears up to 1 year old: Human Years = Bear Years × 5.5
- For bears older than 1 year: Human Years = 5.5 + (Bear Years − 1) × 4.27
These equivalencies vary slightly by species (black, brown, polar), nutrition, and habitat.
