Angle Conversion Calculator
Convert between degrees, radians, gradians, turns, and more.
Angle Conversion Calculator
An Angle Conversion Calculator is a simple and reliable online tool used to convert angles from one unit of measurement to another instantly. Angles are commonly measured in degrees, radians, gradians, arcminutes, and arcseconds, and converting between these units is essential in mathematics, physics, engineering, construction, navigation, and trigonometry.
Instead of memorizing formulas or doing manual calculations, an angle conversion calculator allows you to enter a value in one unit and instantly get accurate results in other angle units.
What Is Angle Measurement?
An angle represents the amount of rotation between two intersecting lines that share a common endpoint. Angle measurement helps describe direction, shape, and movement in both practical and theoretical applications.
Different fields use different angle units, which is why angle conversion is so important.
Common Angle Units Used in Conversions
Degrees (°)
Degrees are the most widely used angle unit in everyday math and geometry. A full circle contains 360 degrees.
Radians (rad)
Radians are commonly used in trigonometry, calculus, and physics. One full circle equals 2π radians.
Gradians (gon)
Gradians divide a circle into 400 equal parts and are sometimes used in surveying and engineering.
Arcminutes (′)
One degree equals 60 arcminutes. This unit is often used in astronomy and navigation.
Arcseconds (″)
One arcminute equals 60 arcseconds. Arcseconds are used for very precise angular measurements.
How the Angle Conversion Calculator Works
The Angle Conversion Calculator uses standard mathematical formulas to convert angles accurately between different units. Simply input the angle value, select the original unit, and the calculator instantly displays the converted values.
This tool eliminates calculation errors and saves time, especially when working with complex angle values.
Angle Conversion Formulas
Below are the most commonly used angle conversion formulas:
Degrees to Radians
Radians = Degrees × π ÷ 180
Radians to Degrees
Degrees = Radians × 180 ÷ π
Degrees to Gradians
Gradians = Degrees × 10 ÷ 9
Gradians to Degrees
Degrees = Gradians × 9 ÷ 10
Degrees to Arcminutes
Arcminutes = Degrees × 60
Degrees to Arcseconds
Arcseconds = Degrees × 3600
Example Angle Conversions
45 degrees to radians
45 × π ÷ 180 = π ÷ 4 radians
90 degrees to gradians
90 × 10 ÷ 9 = 100 gradians
1 radian to degrees
1 × 180 ÷ π ≈ 57.2958 degrees
