Formula
where:
- BCPhysics = ballistic coefficient as used in physics and engineering
- M = mass
- A = cross-sectional area
- Cd = drag coefficient
- ρ (rho) = average density
- l = body length
This definition is not the same as the BC used by bullet manufacturers. This is the BC as defined by and used in physics and engineering. Although it would not be incorrect to describe the behavior of bullets using this equation, the BC obtained from this equation would not give the same value as the BC from a bullet manufacturer because their value is a comparison to the G1 bullet model.

Famous quotes containing the word formula:
“For the myth is the foundation of life; it is the timeless schema, the pious formula into which life flows when it reproduces its traits out of the unconscious.”
—Thomas Mann (1875–1955)
“Hidden away amongst Aschenbach’s writing was a passage directly asserting that nearly all the great things that exist owe their existence to a defiant despite: it is despite grief and anguish, despite poverty, loneliness, bodily weakness, vice and passion and a thousand inhibitions, that they have come into being at all. But this was more than an observation, it was an experience, it was positively the formula of his life and his fame, the key to his work.”
—Thomas Mann (18751955)
““It’s hard enough to adjust [to the lack of control] in the beginning,” says a corporate vice president and single mother. “But then you realize that everything keeps changing, so you never regain control. I was just learning to take care of the belly-button stump, when it fell off. I had just learned to make formula really efficiently, when Sarah stopped using it.””
—Anne C. Weisberg (20th century)
