Angle Converter
Convert degrees, radians, and gradians for trigonometry, navigation, engineering drawings, and game development coordinate systems.
Formula
radians = degrees ร (ฯ / 180) | gradians = degrees ร (10 / 9)
Degrees are used as the base for conversion. A full circle is 360ยฐ, 2ฯ radians, or 400 gradians. Each scale divides the circle differently but measures the same rotation.
Example
- Convert: 1 m ร 3.28084= 3.28 ft
Result: 1 meter = 3.28 feet
Frequently Asked Questions
How many radians are in 180 degrees?
180 degrees equals ฯ radians (approximately 3.14159). This is a half rotation.
When should I use radians instead of degrees?
Radians are preferred in calculus, physics, and programming because trigonometric functions in most languages expect radian input by default.
What are gradians used for?
Gradians divide a right angle into 100 units. They appear in some surveying and European engineering contexts but are less common than degrees or radians.
