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.

300mm = 30 cm
2.54 ^ 3.64 = 29.75738257
29.75738257 = 1428.354364
E-factor = 1428
Better?
