Armor value 48 = 2.54cm of Rolled Homogenous Steel. (RHA)
2.54cm = 25.4mm
Penetration for 85mm HVAP-T is 180mm.
180 divided by 25.4 = 7.086614473
Rounded to 7.087 inches of RHA
7.087 divided by 2.54 = 2.79000558
Rounded to 2.80 doublings from 2.54
AV 48 * (2.54^2.80) = 652.7932332
Rounded to 653.
Efactor for HVAP-T is 653.
Somebody please fact check that as I am unsure. Thanks!
