Untitled[edit]

Pretty sure that the diameters for a proton and atomic nucleus are up to an order of magnitude too big here, i.e proton >~ 1fm but < 10fm and atomic nucleus diameter << 100fm. Going by the standard empirical formula listed in http://hyperphysics.phy-astr.gsu.edu/hbase/nuclear/nucuni.html#c4, even a uranium nucleus is only 7.8fm! I don't usually like to change these things but I will here.

radii is now 0.88 +-0.01 http://phys.org/news/2016-08-deuterium-nucleus-proton-radius-puzzle.html

If it's to be moved to Femtometre, the redirect there should be deleted first, then the page moved. --User:Docu

Since meter is at metre, for consistency's sake all the others should be so spelled. Rmhermen 19:18, Dec 8, 2003 (UTC)

Let's move it there! I already listed the redirect at Wikipedia:Redirects for deletion -- User:Docu

Fine. I was only doing this because I can't do deletes and BOTH pages have a significant edit history, which IS KEPT by doing the cut and paste. Doing the delete and move only keeps one lot of history. -- So, when does it get deleted so the move can happen? -- SGBailey 2003-12-09

The symbol for fermi is F. The sources for it being fm are wrong. -- ikacer 2013-09-07 — Preceding unsigned comment added by 74.76.130.117 (talk) 20:06, 7 September 2013 (UTC)[reply]

F is the symbol for farad, so it wouldn't be fermi. Everyone I know uses fm for fermi. Gah4 (talk) 00:59, 27 March 2021 (UTC)[reply]

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Femtometre. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Added archive https://web.archive.org/20110523023532/http://metricsystemconversion.info:80/fermi-to-femtometer-fm.html?func=detail to http://metricsystemconversion.info/fermi-to-femtometer-fm.html?func=detail

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Spelling of Femtometre[edit]

Presently, the topic is spelled the British way, "Femtometre." If I understand the current way the wind is blowing in en.Wikip, we should spell it using the American way. Is this no longer the case? Or did I just find an unrevised article? Honor, color, and favor forever, -- Srwalden (talk) 18:12, 29 March 2016 (UTC)[reply]

Removed duplicate sig. -- Srwalden (talk) 18:16, 29 March 2016 (UTC)[reply]

first[edit]

Which came first, using the fm symbol, fermi or femtometre? I presume it wasn't an accident. Gah4 (talk) 01:00, 27 March 2021 (UTC)[reply]
