Quick answer:<\/strong> Use math.degrees() for one scalar angle and numpy.degrees() for arrays. Both convert radians to degrees by multiplying by 180 divided by pi. Keep full precision while an angle participates in calculations, then round only when formatting a label or report.<\/p>\n

\"Python
Use math.degrees() for a scalar and numpy.degrees() for arrays; convert at the presentation boundary and round only for display.<\/figcaption><\/figure>\n

The easiest way to convert radians to degrees in Python is math.degrees(angle)<\/code>. It converts an angle measured in radians into the matching degree value.<\/p>\n

The main references are Python’s math.degrees documentation<\/a>, the math.radians documentation<\/a>, and NumPy’s numpy.degrees documentation<\/a>.<\/p>\n

Radians and degrees measure the same angle with different units. A full circle is 2 * pi<\/code> radians or 360<\/code> degrees, so pi<\/code> radians equals 180<\/code> degrees.<\/p>\n

Use math.degrees()<\/code> for one number. Use NumPy when you need vectorized conversion across many values.<\/p>\n

The most common mistake is mixing units in the same calculation. Trigonometric functions such as math.sin()<\/code> and math.cos()<\/code> expect radians, while user-facing reports often show degrees.<\/p>\n

Convert only at the boundary where the unit changes. That might be when reading input, printing output, or passing data into a library that expects a specific angle unit.<\/p>\n
