Angle Converter (Degrees, Radians, Gradians)

Angles are an essential concept in mathematics, physics, engineering, navigation, astronomy, and computer graphics. An angle represents the amount of rotation between two intersecting lines or planes. Because different fields use different units to measure angles, converting between them becomes necessary.

The CalcAndSave Angle Converter is an easy-to-use online tool that allows users to instantly convert between multiple angle measurement units. Instead of performing complicated calculations manually, the converter provides quick and accurate results.

This tool supports several angle units including:

• Degrees (°)

• Radians (rad)

• Gradians (grad)

• Arcminutes

• Arcseconds

Angle conversions are commonly used in fields such as engineering, architecture, navigation, trigonometry, robotics, and computer graphics. Whether you are solving mathematical equations, programming graphics, or working with navigation systems, this angle converter helps simplify the process.

What is an Angle?

An angle is formed when two lines intersect at a common point known as the vertex.

Angles represent the amount of rotation from one line to another.

Angles are typically measured using three main systems:

• Degrees

• Radians

• Gradians

Each of these measurement systems is used in different scientific and mathematical applications.

For example:

• Geometry problems often use degrees

• Trigonometry and calculus frequently use radians

• Surveying may use gradians

Angle Conversion Formula

Angle conversions use fixed mathematical relationships between units.

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

These formulas are built into the CalcAndSave Angle Converter, allowing users to perform conversions instantly.

Example Angle Conversions

Example 1

Convert 90 degrees to radians

Radians = 90 × π ÷ 180
= 1.5708 radians

Example 2

Convert 1 radian to degrees

Degrees = 1 × 180 ÷ π
= 57.2958 degrees

Example 3

Convert 100 gradians to degrees

Degrees = 100 × 9 ÷ 10
= 90 degrees

Example 4

Convert 180 degrees to radians

Radians = 180 × π ÷ 180
= π radians

Common Angle Units Explained

Degree (°)

The degree is the most commonly used unit for measuring angles. A full circle contains 360 degrees.

Radian (rad)

Radians are widely used in mathematics and physics, particularly in trigonometry and calculus.

One complete circle equals 2π radians.

Gradian (grad)

Gradians divide a circle into 400 equal parts and are sometimes used in surveying and engineering.

Arcminute

One degree equals 60 arcminutes.

Arcsecond

One arcminute equals 60 arcseconds.
