1 full rotation = 360° = 2π rad = 400 grad = 6283.19 mrad = 21600′ = 1296000″
1° = π/180 ≈ 0.01745 radians.
Gradians divide a right angle into 100 parts. 1 full circle = 400 grad. Used in surveying.
1 mrad = 0.001 rad. Used in military and firearms. 1 mrad ≈ 0.0573°.
60 arcminutes = 1 degree. 60 arcseconds = 1 arcminute.
Radians for math/physics formulas. Degrees for everyday angles and engineering drawings.
