It's more complicated than that and we can thank the telecommunications 
industry for it.

A 64 kbit/s phone line is actually 64000 bits per second (one packet of 8 
bits at 8000 times per second). However, when you put 32 of them 
together, you get 2048000 bits per second or 2 Mbit/s (exact).

Then again, there's a lot of overhead in any transmission protocol, so 
anyone trying to make exact calculations is nuts.
