Horse Age Conversion Formula

For converting horse age in human years, the approximation can vary based on the breed, size, and specific care of the horse. However, a general approximation often cited is:

1. The first year of a horse’s life is equivalent to about 6.5 human years.
2. The second year of a horse’s life is equivalent to about 5 human years.
3. Every year after that is equivalent to about 2.5 human years.

This approximation is based on the fact that horses mature more rapidly in their early years compared to humans.
