Radians and degrees describe the same angle using different scales. Since π radians equals 180 degrees, multiplying by 180/π converts radians to degrees.
⚠Enter a decimal radian value. For exact π-based inputs, convert the coefficient of π manually before entering if needed.
How Radians to Degrees Conversion Works
A full rotation is 2π radians or 360 degrees. The conversion factor 180/π maps the radian scale back to degrees.
Radian Measure
