About these units
Arcminute
The arcminute (minute of arc, symbol ′) was introduced alongside the degree in ancient astronomy. Hipparchus and Ptolemy used it in their star catalogues. The name comes from the Latin pars minuta prima (first small part).
Degree
The degree has been the primary angular standard since Babylonian astronomy. Its 360-part division of the circle is used universally in navigation (latitude/longitude), surveying, cartography, and everyday angle measurement worldwide.
