## How does this ERA calculator work?

This is a sports tool designed to retrieve the earned run average (era) used in baseball statistics by taking account of total number of earned runs and of number of innings pitched.

Before presenting the formula used it is important to understand what ERA is. This is defined as a common baseball statistical indicator that shows the average number of earned runs a pitcher will give up a nine-inning game. It is calculated by multiplying by nine the result that came by dividing the total number of earned runs by the number of innings pitched and this is the formula the ERA calculator uses:

**Earned run average (ERA) = 9 * Total no. of earned runs / No. of innings Pitched**

## Example calculation

Let’s take the case of 19 earned rounds in 87 innings pitched. This means an ERA value of approximately 1.97.
