How the conversion works
Every unit is converted through the degree. A full circle is 360°, 2π radians, 400 gradians or 6,400 NATO mils.
rad = ° × 0.01745329
1 ° = 0.01745329 rad
Degrees to radians
Multiply degrees by π/180 to get radians, and radians by 180/π to get degrees. 90° = π/2 ≈ 1.5708 rad.
