Common angle conversion mistakes
-
The calculator is in the wrong mode. SIN() in a spreadsheet, Math.sin in code and a calculator in radian mode all read 90 as radians, so sin(90) gives about 0.894, not 1. Convert degrees to radians first, or switch the calculator to degree mode.
-
Gradians and degrees are easy to mix up, since both show as plain numbers on the instrument. A right angle is 90° but 100 gon, and 1 gon is smaller than 1°. Check the unit setting on the instrument.
