Maybe I'm missing something, but what does the reference to 1023 of Carbon-12 have to do with the tera- SI prefix?

Nothing at all that I can see. It might belong under yotta-, but even then I'm not sure that one can stick SI prefixes before just any word whether or not they're SI units. (Can one say that the world population currently stands at 6.6 gigapeople?) I'm removing it anyway. Vilĉjo 10:30, 26 July 2007 (UTC)

I don't have a link beyond an education in ancient Greek, but it is more likely to be an evolution from the ancient Greek τέρας which means 'monstrous' and 'huge'. To say 'monster' is rather open to alternate interpretation with some hairy scary creature. [[1]] —Preceding unsigned comment added by (talkcontribs)


This article has a different (lowercase) start from all the other SI prefixes. Either they ought to change or this article ought to change - for consistency's sake. Is there any reason I've missed? Ian Cairns (talk) 12:31, 29 March 2009 (UTC)

Broken Link[edit]

The dates are a broken link — Preceding unsigned comment added by (talk) 21:35, 15 July 2011 (UTC)

Speculation about etymology[edit]

The current etymology for tera through to yotta is simply random unsourced speculation and I am removing it henceforth. In any case, exa, zetta and yotta look more like Greek letters (eta, zeta, iota) than Greek numbers (hex, hepta, okto), and very little like Latin (sex, septem, octo). Wikipedia articles are not open to half-baked etymological fantasy on the part of editors. Zargulon (talk) 16:39, 2 November 2011 (UTC)

I also removed the "Teras - monster" etymology, which was sourced to a broken weblink which did not seem to be a reliable authority even when it was not broken. It is much more likely to come from the numerical prefix for four, "tetra", similarly to peta < "penta" (five). Zargulon (talk) 16:44, 2 November 2011 (UTC)
