Frequently Asked Questions
How many radians are in 180 degrees?
180 degrees = π radians ≈ 3.14159 radians. This is the most important angle conversion in mathematics and physics.
What is a gradian?
A gradian (also called gon or grade) divides a right angle into 100 parts, so a full circle = 400 gradians. Used mainly in surveying and civil engineering.
What is the difference between arcminute and arcsecond?
1 degree = 60 arcminutes = 3600 arcseconds. These tiny units are used in astronomy, GPS coordinates, and optical instruments.
