What's the approximate equivalent of a size 4, 6, 8 quill in rounds?

The 4, 6, and 8 quill will approximately equal the 16, 18, and 20 rounds in the Princeton Neptune line. This will not necessarily be the case for other brands, or even other Princeton lines, because brush sizes are not standardized. The diameters are 10mm, 11mm and 13mm respectively, and the lengths of the tufts will be 37mm, 38mm, and 40mm.
