In data communications, a kilobit is a thousand bits (1,000) bits. It's commonly used for measuring the amount of data that is transferred in a second between two points. Kilobits per second is usually shortened to Kbps (or kbps). For example, 64kbps is 64,000 bits per second.
1 kb/s = 1000 b/s
1 KB/s = 1024 B/s
1 KB/s = 8.192 kb/s
1 kb/s = .1221 KB/s
The lowercase b usually stands for bits while the uppercase B stands for bytes.
To find your theoretical download speed for your line, divide your advertised speed by
64kbps / 8.192 = 7.8125 KB/sor by 10 to include overhead:
64kbps / 10 = 6.4 KB/s
