Enter the total number of cells and the volume (mL) into the Pitching Rate Calculator. The calculator will evaluate the Pitching Rate.

## Pitching Rate Formula

The following two example problems outline the steps and information needed to calculate the Pitching Rate.

PITR = #C / V

• Where PITR is the Pitching Rate (cells/mL)
• #C is the total number of cells
• V is the volume (mL)

## How to Calculate Pitching Rate?

The following example problems outline how to calculate Pitching Rate.

Example Problem #1:

1. First, determine the total number of cells.
• The total number of cells is given as: 1,000.
2. Next, determine the volume (mL).
• The volume (mL) is provided as: 14.
3. Finally, calculate the Pitching Rate using the equation above:

PITR = #C / V

The values provided above are inserted into the equation below and computed.

PITR = 1000 / 14 = 71.428 (cells/mL)

Example Problem #2:

For this problem, the variables required are provided below:

total number of cells = 2,000

volume (mL) = 13
