I could argue that there are benefits converting to the metric system. Thanks to Festool and the 32 system, I'm in the process of picking it up. I still can't imagine what 768mm looks like without converting it to inches but once I've made a cut-list in metric the rest is cake. Obviously metric and inch rules are equally accurate but I've found it helping me to be more accurate. It's hard to explain but this mid-40s American is a recent convert and I'd encourage others to give it a whirl. If you're making cabinets I don't know how you'd not use metric.
