Total Kinetic Energy (KE) = .5 mass x velocity^2.
So, A .45 caliber bullet weighing 15 grams traveling at 288 meters per second (.015kg/2)x288mps^2=619 joules of energy. For comparison, consider when a 139 lb man falls out of bed for one meter: (63.04kg/2)x9.81mps^2= 618.5 joules of energy.
So, being shot by a .45 is roughly equivalent to falling out of bed for a mid-sized man; the difference being that the bullet's force is centered around a dime-sized area. But what about the 30 millimeter round weighing .91 kilograms and traveling at 1500 meters per second? (.91kg/2)x1500^2= 1,023,750 joules of energy.
Divide 1,023,750 by 619 and you get 1653.87, or the equivalent of 1,653.87 .45 caliber bullets hitting you at once, or [1,023,750/63.2kg/9.81=] that 139 lb man falling 1651.23 meters or a little over a mile.
