Besides the obvious answer to multiplying by 1024 (or 1000 if you want to be the correct SI)?
AFAIK top, ps, etc. get information from reading / proc / [PID] / status or something like that. Information about which reports in KB. Therefore, I would have guessed that the answer to your question is no. Not that a positive answer would be useful, since memory is allocated from the kernel at the page level of detail, and the minimum file size for Linux is 4 KB, so you won’t get more “resolution” by receiving memory consumption in bytes.
