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 217.235.169.25 (talk) 23:09, August 24, 2007 (UTC)

[edit]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
[edit]"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?
[edit]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#Consolidate_all_the_little_articles 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)
