300 divided by 25.4 = 11.81102362

Rounded to 11.811 inches of RHA

11.811 divided by 2.54 = 4.6500093

Rounded to 4.65 doublings from 2.54

AV 48 * (2.54^4.65) = 3661.997299

Rounded to 3662

Efactor for HEAT-FS is 3662.


Nope. Can't be right. I am screwing up the math in figuring how many times a penentration has doubled from the original 2.54 cm.

Armor value 48 = 2.54cm of Rolled Homogenous Steel. (RHA)

2.54cm = 25.4mm

Penetration for 85mm HEAT-FS is 300mm.

300 divided by 10 = 30 centimeters (not inches!)

30 cm divided by 2.54= 11.811023622047244 inches. (Almost a foot!)


Now where I run into a problem. What was doubled and doubled again to reach 11.811023622047244?

Time to stop.
