Radians (decimal)

degrees = radians × (180/π)

π/6

= 30°

π/4

= 45°

π/3

= 60°

π/2

= 90°

2π/3

= 120°

= 180°

3π/2

= 270°

2π

= 360°

You can enter decimal radians (like 1.5708) or use π notation by entering numerator and denominator separately.

Memorize key values: π/6=30°, π/4=45°, π/3=60°, π/2=90°, π=180°, 2π=360°.

Since π radians = 180 degrees, multiplying by 180 and dividing by π converts radians to degrees.
