Angle Converter
Convert Between Degrees, Radians, Gradians, and Other Units Instantly
What is an Angle?
An angle is the figure formed when two rays (or lines) meet at a common point.
It measures the amount of rotation between the two lines.
The most common unit of angle is the degree (°), but other units like radians, grads, and minutes/seconds are also widely used.
Why Use an Angle Converter?
- Quickly switch between degrees, radians, grads, and arcminutes/arcseconds.
- Essential for mathematics, physics, navigation, and engineering.
- Saves time by eliminating manual calculations.
Common Applications
- Mathematics & Geometry – Angles in shapes and trigonometry.
- Physics & Engineering – Rotational mechanics, waves, oscillations.
- Navigation & Surveying – Latitude/longitude, bearings.
- Astronomy – Celestial coordinates.
- Computer Graphics – Rotations, 3D modeling, animations.
How to Use the Angle Converter
1. Enter the value in your chosen unit (e.g., degrees).
2. Select your starting unit.
3. Instantly view results in all supported angle units.
Supported Units
- Degrees (°)
- Radians (rad)
- Gradians (gon/grad) – 400 grads = 360°
- Minutes (′) – 1° = 60′
- Seconds (″) – 1′ = 60″
- Turns (revolutions) – 1 turn = 360°
- Milliradians (mrad) – used in ballistics & optics
Example Conversions
- 1 rad ≈ 57.2958°
- 180° = π rad
- 1° = 60 minutes = 3600 seconds
- 1 grad = 0.9°
- 1 turn = 360° = 2π rad
