About Degree

The degree is a measurement of angle equal to 1/360 of a full rotation. It is the most commonly used unit of angular measurement.

Common uses: navigation, geometry, construction.

About Gradian

The gradian (gon) is a unit of plane angle. One gradian equals 0.9 radians. UnitConvertLab converts it against every other angle unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: angle calculations, engineering and science, education.
