Bps (with uppercase 'B') represents bytes per second. Use of Bps, KBps, or MBps is avoided in networking as computer architectures implement a byte with differing numbers of bits; some use four bits, most use eight bits, and a few use neither.
Because eight-bit byte architectures dominate today, converting from Bps to bps involves only multiplying by eight. However, it's too easy to confuse the two acronyms and best to use 'bps' consistently.
