About Angle Converter

Angle Converter swaps between degrees (a full circle is 360°), radians (2π ≈ 6.283), gradians (400 in a full circle, used in surveying), and turns (1 full loop = 1). Useful for trig homework where calculator mode differs between radians and degrees, geographic surveyed angles quoted in gradians, and CNC and robotics where radians are the standard. Full precision; runs locally so your inputs never go anywhere.

Best for

  • Trig homework where your calculator is in the wrong mode
  • Surveying angles between gradians and degrees
  • CNC, robotics, and physics work that uses radians as the SI standard

Pros

  • +Degrees ⇄ radians ⇄ gradians ⇄ turns in one panel
  • +Full IEEE-754 precision in π-based conversions
  • +Local JavaScript only; no signup, no uploads, works offline

Cons

  • −Doesn't include DMS (degrees · minutes · seconds) format
  • −No mil (military 6400) outside the basic scales

Frequently Asked Questions

How many degrees in a radian?
1 radian = 180/π ≈ 57.296°. A full circle is 2π radians ≈ 6.283 rad. The panel uses the exact full-precision factor so chained conversions stay accurate.
What's a gradian?
A gradian (grad or gon) splits a full circle into 400 units instead of 360. Surveying and some European mapping traditions use gradians; converting to degrees is × 0.9. The panel handles this factor cleanly.
Can I convert degrees · minutes · seconds (DMS)?
Not yet. The panel reads decimal degrees. To convert DMS to a decimal, divide minutes by 60 and seconds by 3600, then add — then enter the decimal here.
Why include turns?
A 'turn' is one full loop — useful in robotics, signal processing, and game development where rotations repeat. 1 turn = 360° = 2π rad = 400 grad.
Are my angle inputs uploaded?
Never. Conversion is fully local JavaScript in your browser. Surveying notes, trig homework, and CNC values stay on your device.
