What does this tool do?

A full circle is 360°, 2π radians, 400 gradians or one turn. Radians are the natural unit in maths and physics; degrees are everyday; gradians appear in surveying.

Arcminutes and arcseconds divide a degree into 60 and 3,600 parts — used in astronomy, navigation and optics.

Why use it?

  • Seven angle units.
  • Full-precision π.
  • Common values table.
