Line speed Vs data transfer rate

Speed:

 Browsers and other file transfer agents tend to show speed in terms of kilobytes per second, usually with one or two decimal places.  Thus, you may see your browser report a "Transfer rate:" being "XX KB/Sec", (along with the flying paper graphic as displayed to the right. )

So.. bytes and bits? I just divide by 8 then?    

TCP has an overhead in transmission that can be as low as 3%,
but ATM overhead is more like 10% ..
So you can expect to lose 13% at least when counting application data transfer rate.

Making up a rule of thumb here:

Given a broadband line speed, dividing by 8 and taking off 13% is a reasonable estimate of the maximum likely data download speeds (in bytes of data) you will manage to get.
