I'd implement byte counters in base 2 (KB, MB, etc). MiB is annoying to us old grumpy folk, but I'd live with it.
But, I absolutely hate that object count is in base 2. 1kg is not 1024 kilograms. We have a reason for bytes to be in base 2. Very few other things are expected to be in base 2. A normal person looking at ceph status would interpret 1M objects as one million.

I received a bug report from a user that printing object counts with a base 2 multiplier is confusing (I agree) so I opened a bug and https://github.com/ceph/ceph/pull/19117. In the PR discussion a couple of questions arose that I'd like to get some opinions on: - Should we print binary unit prefixes (MiB, GiB, ...) since that would be technically correct? - Should counters (like object counts) be formatted with a base 10 multiplier or a multiplier woth base 2? My proposal would be to both use binary unit prefixes and use base 10 multipliers for counters. I think this aligns with user expectations as well as the relevant standard(s?).
