Facts About Internet Speed.
1Byte = 8 bits
1Kilobit (Kb) = 1000 bits
1megabit (Mb) = 1000 Kb
1KiloBYTE (KB) = 1000 BYTES
1MegaByte (MB) = 1000 KB
So
1 KB= 8 Kb
and
1 MB= 8 Mb
Let's take an example, If your service provider says your download speed is 1 Mb/s. To figure out how fast this is in Megabytes/s, all you do is divide by 8. so 1/8= .125, or 125 KB/s. This works in reverse too. Lets say you are downloading a file at 125 KB/s. Multiply this by 8. So 125x 8= 1000 Kb/s or 1 Mb/s, This works with Kb and KB too
