I'm not sure what conversion table you're using, but the wiget on my Mac says 230mm = 9.055 inches. It shows one inch as being 25.4 mm. Just to make sure, I looked at a metal rule with both scales and it's the same. Using the same wiget for a standard V8 .87 diameter bar gives 22.098 mm. An .89 bar (heavy duty or AC) = 22.6, and the Mopar Performance .920 bar = 23.368mm. Finally the HD/race 1.06 aftermarket bars made by Firm Feel are 26.924mm.
