Radians to Degrees Converter

Multiply radians by 180/π — about 57.2958 — to get degrees. The result is also shown in degrees, minutes and seconds.

1 rad = 57.2957795131°

Formula

1 rad = 57.2957795131 °

degrees = radians × 57.2957795131

Worked example

Convert 2.5 radians to degrees

  1. Multiply by 57.2957795131
  2. 2.5 × 57.2957795131 = 143.239

2.5 rad = 143.239 °

Good to know

One radian is the angle at the center of a circle when the arc length equals the radius — about 57.3°. For multiples of π, replace π with 180°: 3π/4 rad = 3 × 180° ÷ 4 = 135°. The scientific calculator accepts pi in expressions if you need to evaluate one.
