Frequently asked
Why so many angle units?
Degrees for everyday geometry, radians for math and physics (natural units for trig), gradians for surveying (400 in a circle → decimal-friendly), turns for rotation (1 turn = 360°), arcminutes and arcseconds for astronomy and precision optics.
When would I use gradians?
Almost never — but many scientific calculators still have a GRAD mode. It was a French Revolution-era decimalization attempt that never caught on outside surveying.
