+37159 A gradian is 9/10 of a degree sooo if you have 100 gradians 100 (9/10) = 90 degrees
or to go to gradians from degrees multiply by 10/9 90 degrees x 10/9 = 100 gradians
+26 A gradian is a seperate measurement unit for angles, it's not what you're looking for.
Not many people use gradians because you can just use radians.
+37159 A gradian is a a different unit of measure for angles....a full circle is 400 gradians (360 degrees). I assumed that is what you meant to ask and just misspelled (as so often happens on this website) 'gradian'
IF you really meant GRADIENT of an angle, it is most likely the tangent of the angle (slope).
