Angle Converter FAQ
What is an angle converter?
An angle converter converts angle units such as degrees, radians, and gradians. It is useful for trigonometry, geometry, navigation, engineering, and physics calculations.
How do I convert degrees to radians?
Enter a value, choose degrees as the source unit, and choose radians as the target unit. This is commonly used in trigonometry, geometry, and math problems involving angles.
How do I convert radians to degrees?
Enter the radian value, select radians as the source unit, and select degrees as the target unit. For example, π radians equals 180 degrees.
Can I enter pi-based radian values like pi/2?
Yes. You can enter regular numbers or pi-based expressions such as pi/2, pi, 2pi, or 1/3pi when converting radians.
What is the difference between degrees, radians, and gradians?degrees divide a full circle into 360 parts, radians measure angles using the radius of a circle, and gradians divide a full circle into 400 parts.
When should I use radians instead of degrees?
Use radians for most advanced math, trigonometry, calculus, physics, and programming calculations. Use degrees for everyday angles, navigation, geometry, and many practical measurements.
Can I use this angle converter for trigonometry and geometry?
Yes. This angle converter is useful for trigonometry homework, geometry problems, navigation bearings, engineering calculations, and converting angles used in formulas or diagrams.
