💡 Did you know?

1 radian = 63.66 gradians (200/π). Gradians were designed so a right angle = 100 gon — convenient for surveyors. A full circle = 400 gradians. European theodolites (surveying instruments) often display angles in gradians, which is why surveyors need to convert between gradians and degrees.
