Talk:Grad (angle)

From Wikipedia, the free encyclopedia

Is it so much easier to add or subtract 100 than 90? This shouldn't be listed as a pro of the gon unit.

yes its MUCH easier to just change the most significant digit rather than mess arround with carries or subtraction tricks. Plugwash 19:14, 4 August 2005 (UTC)

[edit] Gradient

Curiously, MicroSoft did call it "gradient" for a while on its calculator that comes with Windows; my XP version has "Grads". Gene Nygaard 14:31, 25 October 2005 (UTC)

[edit] Move

I've moved this from Gon to Grad. I've never heard it called the "gon" before (and I'm a measurements buff), the refernces given by the article imply that gon is a Scandianvian and possibly German word, dictionary.com does not find gon as a unit of measure.

Looks like ISO standard symbol is "gon" but it's in an annex of a document I don't have....

I very much prefer to go back to gon, the official international standard name for this unit. Markus Kuhn 12:43, 31 October 2005 (UTC)

The French IGN maps still use the term "grade" for the unit of latitude and longitude (at least in their English language documentation). See [1].

[edit] grad

Trigonometry doesn't work nearly as well with grads or gons or whatever you want to call them. The sine of 30 degrees (or pi over 6)is a lot easier to deal with than 33.33333333333333333333 etc. grads - to get the even .5
