Convert an angle into every unit at once

Enter one value and a unit — degrees, radians, gradians (gons), turns, arcminutes, or arcseconds — and read it back in every unit at once. Each input is reduced to a canonical value in degrees (1 turn = 360°, 1 rad = 180/π°, 1 grad = 0.9°), then every output is derived from that base. Decimals and negative angles (such as -90°) are supported, which is handy when translating CSS angle units like deg, rad, grad, and turn.
