Online Angle Converter

Convert degrees radians gradians turns arcminutes and arcseconds in one place with lightning fast accuracy and clean design. Paste values swap units see live results and copy outputs. Ideal for students engineers surveyors developers and teachers. Works offline on mobile and desktop for quick conversions




This Angle Converter helps you translate a measurement from one angular unit to another instantly. It supports everyday units such as degrees and radians, surveying‑friendly gradians (gon), full‑cycle turns, as well as finer subdivisions like arcminutes and arcseconds. For engineering workflows, it includes milliradians (mrad) and microradians (µrad), plus convenient historical fractions like quadrant, sextant, octant, and the point (1/32 turn).

How to use

  1. In the From box, enter the numeric value you want to convert.
  2. Pick the matching unit under the From Unit dropdown (e.g., Degree).
  3. Under To Unit, select the unit you want to obtain (e.g., Radian).
  4. See the To field update immediately as you type or change units.
  5. Use the Swap button to flip directions and back‑convert in one click.

Why it’s accurate

All conversions route through radians as the base unit using well‑known identities: π rad = 180° and 1 turn = 2π rad. The tool formats results to a practical number of decimals and trims trailing zeros, giving you readable values without losing precision.

Tips

  • For very small angles, try mrad or µrad to avoid scientific notation.
  • Surveying or GIS? Switch to grad (400 grads in a full turn).
  • Optics and astronomy often quote arcmin (′) and arcsec (″).

FAQ

What units are supported?
Degree, radian, gradian (gon), turn, arcminute, arcsecond, milliradian, microradian, quadrant, sextant, octant, and point.
How is the conversion performed?
Values are converted to radians, then out to the target unit using exact constant relationships with π.
Why do I see many decimals?
Some unit ratios are irrational, so decimals are approximations. You can round as needed for your report.
Can I reverse the conversion?
Yes. Use the Swap button or just swap the dropdown selections.
Is this suitable for bearings?
Bearings are typically expressed in degrees relative to North. Convert values as needed, but keep the reference convention in mind.
