^^ A little explanation never hurts!
. 260 KBps(Kilo
bytes per second) = 260*8 Kbps= 2080 Kbps(Kilo
bits per second).
So, your speed is 260/1024 = 0.253 MBps (or MegaBytes per second).
OR, your speed can also be written as, 260*8/1024 = 2.031 Mbps (Megabits per second).
Note the capital B for Bytes and small b for bits. That is how they are expressed (according to the convention).
There! That does it!
