Formula A (Standard Units)
W * V^{2} = K * D^{3} ^{(t/d)^n}
Equation Explained
W = Projectile Weight (pounds)
V = Projectile Velocity (ft/sec)
D = Projectile Diameter (inches)
t = Thickness of Armor plate only just perforated (inches)
d = Constant; dependent on projectile/armor plate types. Usually is 10^{6}.
n = index; normally 1.414
