Enter the mass (kg), the drag coefficient, and the cross-sectional area (m^2) into the Ballistic Coefficient Calculator. The calculator will evaluate the Ballistic Coefficient. 

Ballistic Coefficient Formula

The following formula is used to calculate the Ballistic Coefficient. 

Cb = M/ (Cd*A)


  • Cb is the Ballistic Coefficient ( )
  • M is the mass (kg) 
  • Cd is the drag coefficient 
  • A is the cross-sectional area (m^2) 

To calculate the ballistic coefficient, divide the mass by the product of the drag coefficient and the cross-sectional area.

How to Calculate Ballistic Coefficient?

The following steps outline how to calculate the Ballistic Coefficient.

  1. First, determine the mass (kg).
  2. Next, determine the drag coefficient. 
  3. Next, determine the cross-sectional area (m^2). 
  4. Next, gather the formula from above = Cb = M/ (Cd*A).
  5. Finally, calculate the Ballistic Coefficient.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

mass (kg) = 5

drag coefficient = 4

cross-sectional area (m^2) = 7

Cb = M/ (Cd*A) =  ?
