Home Runs Per 9 Calculator

Formula

The formula to calculate the Home Runs Per 9 Innings (HR/9) is:

\[ HR/9 = \left( \frac{HR}{IP} \right) \times 9 \]

Where:

\( HR/9 \) is the home runs per 9 innings.
\( HR \) is the home runs allowed.
\( IP \) is the innings pitched.

What is Home Runs Per 9?

Home Runs Per 9 (HR/9) is a baseball statistic that measures the average number of home runs a pitcher allows per nine innings pitched. This metric is useful for evaluating a pitcher’s susceptibility to giving up home runs and is often used in conjunction with other pitching statistics to assess overall performance. A lower HR/9 indicates better performance in preventing home runs.

Example Calculation

Consider an example where:

Home Runs Allowed (HR): 5
Innings Pitched (IP): 45

Using the formula to calculate the Home Runs Per 9 Innings:

\[ HR/9 = \left( \frac{5}{45} \right) \times 9 = 1 \]

This means that the home runs per 9 innings for this example is 1.
