Default How do you figure the BC?

I have a question. I can't remember how to figure the ballistic co-efficient of a bullet. I wanted to do some trajectories but the program I have wants the BC not just the weight, cal., and MV.
Can anybody help me with the formula. The bullet is a .451 sized to .448, it is 530 grain. thanks
