Gradian: The Fun & Essential Measurement Unit 🌟

Gradian, often abbreviated as gon or grad, is a unit of measurement for angles. Imagine you have a pizza πŸ•, and you want to cut it into equal slices. A full pizza is 360 degrees in conventional measurements, but in gradian, it’s 400 gradians. This makes it easier to divide things into decimal parts, as 100 gradians represent a right angle.

Gradians are crucial in various fields, including surveying, engineering, and navigation. By using a base of 400, calculations become simpler, especially when dealing with percentages and decimal fractions. Think of gradians as the metric system for angles – clean, easy, and efficient!
