arcminute
Degree's smaller part
An arcminute is one-sixtieth of a degree, used to measure angles in astronomy, navigation, and other fields requiring precision.
Just as an hour divides into sixty minutes of time, a degree divides into sixty minutes of arc.
The symbol is a single prime mark (′).
Also called a minute of arc.
