All credit for this post goes to OzIso members BIGGIE and GABRIEL for providing the information in a previous post, I just wanted to compile it and present it so the information was more condensed.

List of sizes (GABRIEL):
G2 = 0.31g
B = 0.55g
2B = 0.75g
3B = 0.95g
4B = 1.20g
5B = 1.85 (Note that 5B and 0.5 are very similar, imo a negligible difference)
0.5 = 1.87
0.8 = 3.00
1.0 = 3.75g
1.2 = 4.50g
1.5 = 5.62g
2.0 = 7.50g
2.5 = 9.05g
3.0 = 11.25g
4.0 = 14.95g
5.0 = 19.50g
