About Gradian and Arcminute

Gradian (grad)

A gradian divides a right angle into 100 grads, so a full circle is 400 grads.

Where it's used: Surveying and some European engineering fields.

Arcminute (arcmin)

An arcminute is 1/60 of a degree.

Where it's used: Astronomy (apparent sizes), optics, and navigation.
