¹ Although this is the usage preferred by several standardisation organisations, multiple symbol and capitalisation variants are used in many documents, so the context must be used to determine the meaning. Note also that some users differentiate between an upper-case 'B' (for byte) and a lower-case 'b' (for bit) in such abbreviations, whilst others do not.
