JBM - Calculations - Drag Function Conversion Terms

Input Data

Ballistic Coefficient
The ballistic coefficient of the bullet and its associated drag function.
New Drag Function
The drag function to convert the above ballistic coefficient to.
Velocity
The velocity at which the ballistic coefficient entered above is defined. If you only have one BC and no velocity information, use the average of the muzzle velocity and terminal velocity so that you get a new ballistic coefficient representative of the velocity range you are using.

Output Data

New Ballistic Coefficient
The ballistic coefficient entered above converted to the new drag function.
Speed of Sound
Mach number for the given velocity and standard atmospheric conditions.
CD of G? Bullet
The drag coefficient for the entered (or converted) ballistic coefficient and drag function.
