What is Degree?

The degree is the most commonly used unit of angle, with one full rotation divided into 360 degrees. This system is believed to originate from ancient Babylonian astronomy, where a year of roughly 360 days suggested dividing a circle into 360 parts. Degrees are used everywhere in daily life: compass bearings, slopes, architecture, and geometry. A right angle is 90 degrees, a straight angle is 180 degrees, and a full rotation is 360 degrees.

What is Gradian?

The gradian, also called the gon, was introduced during the French Revolution alongside the metric system. It divides a right angle into 100 gradians, making a full circle 400 gradians. This unit is primarily used in surveying, especially in France and Germany, where survey instruments may be graduated in gradians. The advantage is that a right angle is exactly 100, simplifying slope calculations. One gradian equals 0.9 degrees.
