About These Units
Degree (°)
A degree (°) is 1/360 of a full rotation, the most widely used angle unit. Degrees measure geographic coordinates, temperature, slopes, and rotations. A right angle is 90°, straight angle is 180°, full circle is 360°. Each degree contains 60 arcminutes.
Arcsecond (″)
An arcsecond (″) is 1/60 of an arcminute or 1/3600 of a degree. Arcseconds measure stellar positions, telescope resolution, and atmospheric seeing. The Hubble Space Telescope resolves about 0.05 arcseconds. GPS accuracy is measured in arcseconds.
