Isn't grade closer to degrees than to radians? [[User:Djbrasier|Djbrasier]] ([[User talk:Djbrasier|talk]]) 15:03, 20 June 2020 (UTC) | Isn't grade closer to degrees than to radians? [[User:Djbrasier|Djbrasier]] ([[User talk:Djbrasier|talk]]) 15:03, 20 June 2020 (UTC) | ||
− | :It's two different things. The "[https://en.wikipedia.org/wiki/Grade_(slope) grade]" of a slope is just the rise divided by the run, commonly expressed as a precentage. It is not an angle measure but the tangent of an angle measure. It is commonly used in North America for surveying and engineering purposes.

"[https://en.wikipedia.org/wiki/Gradian gradian]" is a badly named angle measurement that, worse, is ofter referred to informally as "grade" from "centigrade".It is an angle measure, though a useless one: ten-ninths of the measure in degrees. The gradian is commonly used for surveying and engineering in some parts of Europe. The text in the current explanation confuses them, which is common due to the bad naming of the second measure.

A friend of mine, attempting to do graphic design, once created an approximate golden spiral using the boxes diagram with quarter circles. He then laboriously produced a logo by making copies of the spiral and using pieces of it for each curve. I then informed him that all the curves in his image were just circular segments.
