## Formula:

The formula for calculating K/9 (Strikeouts Per Nine Innings) is straightforward:

Where:

• represents the Strikeouts Per Nine Innings, which is the rate of strikeouts a pitcher averages over nine innings.
• Total Strikeouts is the number of batters the pitcher has struck out during a given period.
• Total Innings Pitched is the total number of innings the pitcher has pitched during the same period.

## How to Use:

## Example:

Let’s illustrate the calculation with a practical example:

Suppose a pitcher has recorded 75 strikeouts over the course of 120 innings pitched during a baseball season. Calculate the pitcher’s K/9 (Strikeouts Per Nine Innings).

Using the formula:

So, the pitcher’s K/9 (Strikeouts Per Nine Innings) is 5.625.
