I'm not sure of your questions. Are they supposed to be separate, unrelated values or do you want them somehow related. 21,435kbps is 21,435 kilobits per second or 21.435 million bits per second, 2.1 Mb is 2.1 Megabits (the M in Mega should be capitalized - small b stands for bits while capital B stands for Bytes, unless there's a typo and then you have to go by context or check with the author). The first expresses a DATA RATE while the second expresses a DATA QUANTITY. The second could be converted to 262,500 Bytes. Converting kbps to Bps may require allowance for communications protocol overhead. As a rule of thumb, I use 10 bits per byte when discussing data flow conversions (a 2 bit overhead - not unusual to have 2-bit overhead - stop bit, parity bit). Converting bits to Bytes of storage, I use 8 bits per Byte. Though there could be overhead in the storage protocol as well.

It should be Mbps or Mb/s (megabits per second) divide by 10 to get the rough MegaBytes per second. kilo is thousands, mega is millions.
