Calculate the Angular Ratio
Calculator for ratios of angles in degrees, arc minutes, arc seconds or decimal degrees. Enter two angles, when entering decimal degrees, arc minutes and seconds can be omitted. The ratio of the two angles will be calculated in one and in two dimensions, as integer ratio and in relation to 1 (rounded to 5 decimal places).
Example: the Sun has an average diameter of approximately 32 arc minutes. Mercury has a diameter of approximately 11 arc seconds at a transit. At a transit of Mercury, the planet has about 1/175 of the solar width and occults about 1/30466 of Sun's surface.
