What Is the Angle Converter?
Angle conversion relates geometric angles across standard scientific, surveying, and astronomical systems.
How Does the Angle Converter Work?
Uses circle partition ratios: 1 rad = 180°/π ≈ 57.2958°, 1 grad = 0.9°, 1 arcmin = 1/60°.
Angle Converter Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
\text{rad} = \text{deg} \times \frac{\pi}{180}
Converts through circular geometric ratios where 360° equals 2π radians.
How to Use the Angle Converter
- Input angle value and choose source and target units.
Step-by-Step Example Calculation
Convert 180 Degrees to Radians
Input Values:
value:180
fromUnit:deg
toUnit:rad
Worked Steps: 180° equals exactly π radians (≈ 3.14159 rad).
