Talk:SI prefix

The article claims that a liter is sometimes "referred to as a 'dumphrey'". I couldn't verify that claim and removed it. AxelBoldt
The powers of two have a new SI standard, IINM. 210 bytes == 1 Kibibyte (1 KiB), 220 bits == 1 Mebibit (1 Mib), 230 bytes = 1 Gibibyte (1 GiB). -- Hari (2002-03-18)

See http://physics.nist.gov/cuu/Units/binary, for instance -- Hari (2002-03-18)

Could you add an explanation to that effect? Such as "KiB should be used instead of KB...". (It's not a SI standard however.) AxelBoldt

Does anyone have an objction to me moving most of the explanation of byte prefixes to Byte prefixes, and leaving just a short paragraph on it here & a link? -- Tarquin 14:45 Jan 12, 2003 (UTC)

I've renamed it to "Binary prefixes". It's used for anything based on the power of 2 (e.g., bits, words), not just bytes. -- Dwheeler 20:12 21 May 2003 (UTC)

"iso" prefix

I've just added this. Gritchka I have to say I've never seen 'iso' mentioned in this context. What's the authority for this?

I've never heard of it. My encyclopedia doesn't give it in the table of SI. Official reference such as http://physics.nist.gov/Pubs/SP811/sec04 doesn't give it. The only link I have found on google about it seems contentious (Star Trek science). It's also faintly ludicrous -- a metre is a metre. What is the point of saying "isometre"? Just to clinch it, the official site http://www.bipm.fr/enus/3_SI/si-prefixes makes no mention of it. I think someone thought "isobar" was a prefix applied to "bar", whereas it's a line of constant value on a map. In short, I can't find any evidence of its existence, rather, I'm finding evidence of its non-existence. It's going. It's gone ;-) -- Tarquin 00:34 Sep 15, 2002 (UTC)
