Talk:Kilobit per second

See http://www.ieee.org/portal/cms_docs_iportals/iportals/publications/authors/transjnl/auinfo07.pdf for a reliable and definite guide on units and SI prefixes!!! IEEE provides the academic and research oriented guide on units.

A capital "K" has NEVER been used for 2^10. That's nonsense. A capital "K" denotes Kelvin and nothing else. —Preceding unsigned comment added by Special:Contributions/ (talk)

It previously read:

"Another unit of data transmission is the kilobyte per second (kBps or kbyte/s) and is one-eighth that of a kilobit per second:

8 kilobit/s = 1 kilobyte/s"

This did NOT appear to be true as the equation contradicted the text.

Text now updated and should read:

"Another unit of data transmission is the kilobyte per second (kBps or kbyte/s) and is eight times that of a kilobit per second:

8 kilobit/s = 1 kilobyte/s"


 * Nope, the number of kilobytes per second is equal to one-eighth of the number of kilobits per second, as one byte is 8 bits. fvw *  03:11, 2005 Apr 28 (UTC)

Ok, let's think about this.

8 bits = 1 byte

8 kilobits = 1 kilobyte

8 kilobits/s = 1 kilobyte/s

1 kilobit/s = 1/8 kilobyte/s

so "the kilobyte per second (kBps or kbyte/s) is eight times that of a kilobit per second", right? - Omegatron 14:13, Jun 20, 2005 (UTC)


 * Yes, so the number of kilobytes per second is equal to one-eighth of the number of kilobits per second. :) – Smyth\talk 14:18, 20 Jun 2005 (UTC)


 * I'm just going to take your word for it, like I took fvw's word for it before. I can't wrap my mind around this completely trival algebra problem.  :-)  Make sure all six articles are consistent, though. - Omegatron 16:56, Jun 20, 2005 (UTC)


 * Or, even better, reword it. It's clearly confusing people. :-)  - Omegatron 16:57, Jun 20, 2005 (UTC)


 * Perhaps the confusing part is that even though they are different numbers...they are equal units. If I'm sending something at 30 kbytes/sec then I'm also sending it at 240 kbits/sec and 30 is one-eigth of 240 but it's the same rate.  Is this rewording less confusing and unambiguous?

==Kilobyte per second==

Another unit of data transmission is the kilobyte per second (kBps or kbyte/s). One kilobyte per second is equivalent to eight kilobits per second since one byte is equivalent to eight bits. Or, since


 * 8 bits = 1 byte

then


 * 8 kilobit/s = 1 kilobyte/s

So:
 * 1 kilobit/sec is one-eight the rate of 1 kilobyte/sec
 * 1 kilobyte/sec is eight times the rate of 1 kilobit/sec

"One kilobyte per second is equivalent to eight kilobits per second"


 * This is really all it needs to say. :-) - Omegatron 19:11, Jun 20, 2005 (UTC)

CD audio
"CD audio: 16 bits/sample/channel * 2 channels * 44,100 samples/second = 1,411,200 bits/s = 1411 kbit/s....but article says 128.....what am I missing here?"


 * 128 is the mp3 compressed "cd quality". - Omegatron 14:09, Jun 11, 2005 (UTC)


 * Ok. I reworded it since all CD audio is uncompressed 16-bit @ 44.1 kHz. Cburnett 15:55, Jun 11, 2005 (UTC)


 * Yeah. Of course, this isn't taking into account the extra encoding information thrown into the CD format.  Just the bare minimum required for the audio in PCM. - Omegatron 20:17, Jun 11, 2005 (UTC)

Merge into Bit rate?
Should this be merged into Bit rate? (Drop a note on my talk page if you reply, I will probably forget to check back here... Thanks) --Wulf 04:37, September 13, 2005 (UTC)


 * We had a similar discussion about kilobit, megabyte, kibibyte, and so on, and decided to keep the articles separate but put a navigational template on them. See Talk:Binary_prefix and other sections after that one.  I made a similar navigation template for the bit rates, and I am happy with the way it is.   — Omegatron 13:39, 13 September 2005 (UTC)
