Answering my own question....................
Taken from the macrumors.com forums:

Here?s a formula to convert ?retail size? to ?actual size.? This assumes 
that the manufacturer is using 1GB = 1,000,000,000 bytes (instead of 1GB = 
1,073,741,824 bytes as they should).

Actual Drive Size = Retail Drive Size * 0.931

This formula is an approximation. Many times they?ll round the drive size 
somewhat, but this gives you a rough idea of the real world space.

For Quick Reference:

36gb = 33.5gb

40gb = 37gb

60gb = 55gb

74gb = 69gb

80gb = 74gb

100gb = 93gb

120gb = 112gb

160gb = 149gb

200gb = 186gb

250gb = 233gb

300gb = 279gb

350gb = 326gb

400gb = 372gb

500gb = 465gb

These are rounded to the nearest gigabyte.
Hope you guys enjoy, let me know if theres any sizes you want added to the 
list.

Good advice is like good paint- it only works if applied.
