Convert radians to degrees instantly by multiplying by 180 over pi, which works out to about 57.2957795131 degrees per radian. Radians are the standard angle unit in math and programming, but degrees are far easier to picture, so this conversion is what you reach for when a calculation or a library returns an angle in radians and you want to understand it in familiar degrees. This tool uses the exact factor, so pi radians correctly becomes 180 degrees and half of pi becomes 90 degrees. Type any angle in radians, including negatives and decimals, and the degree value appears live as you type, carried to several decimals for accuracy. It is handy for trigonometry, physics, game development, and reading angle outputs from code. Because it runs free and instant in your browser, the answer is immediate, your input stays private, and it works offline once loaded.
