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, 53.333kbps is 53,333 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 8.192:
53.333kbps / 8.192 = 6.51 KB/s

or by 10 to include overhead:
53.333kbps / 10 = 5.33 KB/s
