Enter the bird’s actual age and the rate of bird to human years into the calculator to determine the bird’s age in human years. This calculator can also evaluate any of the variables given the others are known.

## Bird Age Formula

The following formula is used to calculate the age of a bird in human years.

BA = B * R

Variables:

- BA is the bird’s age in human years B is the bird’s actual age (in bird years) R is the rate of bird to human years

To calculate the bird’s age in human years, multiply the bird’s actual age by the rate of bird to human years. The rate varies depending on the species of the bird.

## How to Calculate Bird Age?

The following steps outline how to calculate the Bird Age using the formula BA = B * R.

- First, determine the bird’s actual age (B) in bird years.
- Next, determine the rate of bird to human years (R).
- Next, gather the formula from above = BA = B * R.
- Finally, calculate the Bird Age (BA).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

Bird’s actual age (B) = 5 bird years

Rate of bird to human years (R) = 3
