Gradian: The Fun & Essential Measurement Unit π
Gradian, often abbreviated as gon or grad, is a unit of measurement for angles. Imagine you have a pizza π, 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 β clean, easy, and efficient!
Gradian Measurement Table π
Hereβs a handy table to visualize common gradian measurements across various units:
Gradian Unit | Equivalent Degrees | Radians |
---|---|---|
1 Gradian | 0.9 Degrees | 0.015707963 Rad |
100 Gradians | 90 Degrees | 1.57079633 Rad |
200 Gradians | 180 Degrees | 3.14159265 Rad |
400 Gradians | 360 Degrees | 6.28318531 Rad |
