What is a gradian?
A gradian, also called a gon, divides a right angle into 100 parts, so a full circle is 400 gradians. It is used in some surveying work.
What are arcminutes and arcseconds?
An arcminute is one sixtieth of a degree and an arcsecond is one sixtieth of an arcminute. They are used for very small angles in astronomy and navigation.
Is my data sent anywhere?
