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) 

To calculate the pitching rate, divide the number of cells by the volume.

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

Test your knowledge using the equation and check your answer with the calculator..

PITR = #C / V = ?
