Radians to Degrees Online

Updated 2026-07-26

Convert radians to degrees online for free. Enter an angle in radians and SnapTools shows the exact value in degrees instantly, in your browser — nothing is uploaded.

Code speaks radians — atan2(), asin(), every trig function returns them — but people read degrees. A raw radian result like 1.5708 means nothing at a glance until you see it's 90°. This converter does the ×(180/π) math for you with full floating-point precision, so a script's output becomes something you can actually read. For the full family of angle units — gradians, arcminutes, turns — use the Angle Converter.

// how to use

  1. 1 Type or paste an angle in radians into the input.
  2. 2 SnapTools converts it to degrees as you type.
  3. 3 Copy the result, or use the slider for a quick scrub across a full 2π turn.

Is my input uploaded to a server?
No. The conversion runs entirely in your browser, so nothing you enter leaves your machine.
Why would I need to convert a radian value to degrees?
Trig functions and math libraries return angles in radians, but a human-readable result — for a UI, a report, or a design tool — usually wants degrees. This converter bridges that gap.
What's the exact conversion factor?
Radians to degrees is radians × (180 / π). This tool computes it with full floating-point precision, not a rounded π.
Why is one radian about 57.3°?
A radian is the angle where the arc length equals the radius — since a full circle's circumference is 2π times the radius, one radian is 360° / 2π ≈ 57.2958°.
What about converting degrees back to radians?
Use Degrees to Radians, or the full Angle Converter for gradians, arcminutes, and turns.
