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)

Changes have been made to this page

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#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)
