I'm not a fan of the technically correct base 2 units -- they're still relatively rarely used, and I've spent most of my life using kB to mean 1024, not 1000. > - Should counters (like object counts) be formatted with a base 10 > multiplier or a multiplier woth base 2? I prefer base 2 for any dimensionless quantities (or rates thereof) in computing. Metres and kilograms go in base 10, bytes go in base 2. It's all very subjective and a matter of opinion of course, and my feelings aren't particularly strong :-) John > My proposal would be to both use binary unit prefixes and use base 10 > multipliers for counters.
