1 radian equals 57.2958 degrees
How to convert radians to degrees
One full turn is 360° = 2π rad = 400 gon. A minute or second of arc is an angular unit, distinct from time; decimal displays of factors involving π are approximate.
° = rad ÷ 0.01745329252One degree corresponds to 0.01745329252 radians, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.
572.958 ° ≈ 10 ÷ 0.01745329252Radians to degrees conversion table

degree°
One 360th of a full turn. The everyday angle unit.
Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
