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.
Formula
1 rad = 57.2957795131 °
degrees = radians × 57.2957795131
Worked example
Convert 2.5 radians to degrees
- Multiply by 57.2957795131
- 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.
