Talk:Electronvolt

Rather silly question. How many significant digits do we want for unit relations?

For example, the most accurate value known for the relation in this article is

1 eV = 1.602 176 462(63) x 10^-19 J, where the number in parenthesis is the uncertainty of the last two digits.

Why not give that value then? I would prefer a clearer term than "uncertainty" though. Do they mean standard error? AxelBoldt

Yes, estimated standard deviation.

The most recent recommended values are the "1998 CODATA recommended values". Their values and uncertainties can be found in http://physics.nist.gov/cuu/Constants AstroNomer

I appologise for my mistake in editing, I wasnt thinking and assumed you meant Joules even though it said eV.

"Electron volt" yields 44,000 Google hits, "electronvolt" 1650. Is most of the world wrong? Is there an authoritative source for the correct term? If it is "eletronvolt", then we should move the page. Tannin 12:21 May 13, 2003 (UTC)

Authoritative source: NIST See: http://physics.nist.gov/cuu/Units/outside

Please move the page, I do not know how to do it.

If NIST have got it wrong, there is little hope for the rest of us! I'll move the page in a moment. This can be one more of those little things that we at Wikipedia have got right, even though the majority get it wrong. Given enough eyes to look for them, sooner or later there will be no more mistakes left here. Well spotted, Vargenau. :) Tannin
