## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/angle-conversion-calculator/?value=180&fromUnit=degree&toUnit=radian

## Inputs
- value: Angle; type=number; required; default=180
- fromUnit: From unit; type=select; required; default=degree; values=degree|radian|gradian|turn|arcminute|arcsecond
- toUnit: To unit; type=select; required; default=radian; values=degree|radian|gradian|turn|arcminute|arcsecond

## Outputs
- result: Converted angle; format=number; primary
- degrees: Equivalent degrees; format=number
- radians: Equivalent radians; format=number

## Formula
degrees = value × degrees-per-source-unit; result = degrees ÷ degrees-per-target-unit

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
