How many bits are there in 1.2 Mb?

The 'k' in 'kb' stands for 'kilo', which means 1000. Therefore there are 1000 bits in a kb.

Close, but didn't really answer the specific question (see 'bits' vs 'byte'). It's really important when you get into specific record-sizes, and/or lots of records, when sizing a DB, pipe-sizes, network-sizing, traffic and whatnot, that one calculate exactly, and off by this factor (see below) could be (or become) serious matters.

K in computing means 2^10th power, in BYTES, so 1K = 1024 BYTES. Then 1 byte = 8 bits (don't EVEN get into Words, dbl-Words, quad-Words, or any hardware-dependent stuff like that).

So, then 1K * (1024 BYTES/1K) * (8 bits/1BYTE) = 8192 BITS in a kiloBYTE.
