There is a big difference between 56 kbps or 56 kBps. If you are writing a technical paper and you are a programmer from SAP, make sure you get it right because the difference between bits and bytes is huge.
The correct convention is to use a small “b” for bits, and capital “B” for bytes and there are eight bits to a byte.
56 kbps = 56000 bits per second
56 kBps = 8 * 56000 = 448000 bits per second
Spread the word.
