Calculation·conversion criteria
Convert degrees to deciradians and gradians.
Input example
1 degree = 0.01745329252 radian
A full circle of 360 degrees is 2π radians, so 180 degrees is π, and 90 degrees is π/2 radians. The radian result is displayed as the approximate value of π.

Frequently Asked Questions
Does it automatically reduce the angle if it exceeds 360 degrees?
No. It converts the angle including the number of rotations directly. 720 degrees is two revolutions or 4π radians. To compare only directions, calculate the remaining one revolution separately.
