Angles are widely used in mathematics, physics, engineering, navigation, and surveying. While gradians (also called gons or grads) are convenient in metric-based calculations, degrees are more common and intuitive for general understanding.
Gradian to Degree Calculator
What is a Gradian?
A gradian divides a full circle into 400 equal parts.
- 1 full circle = 400 gradians
- 100 gradians = right angle
- 200 gradians = straight angle
Gradians are often used in surveying, civil engineering, and mapping, where decimal-based measurements simplify calculations.
What is a Degree?
A degree divides a full circle into 360 equal parts.
- 1 full circle = 360 degrees
- 90° = right angle
- 180° = straight angle
Degrees are more familiar for everyday use, navigation, geometry, and general mathematics.
Formula for Conversion
The formula to convert gradians to degrees is:
Degree = Gradian × (360 / 400)
or simplified:
Degree = Gradian × 9 / 10
Examples:
- Convert 200 gradians to degrees:
200 × (360 / 400) = 180° - Convert 100 gradians to degrees:
100 × (360 / 400) = 90° - Convert 50 gradians to degrees:
50 × (360 / 400) = 45°
