This program allows you to convert one of many general degree systems into another. For example, you can convert percentages from 0-100 to degrees 0-360, decimal hours to hours, minutes, and seconds, radians to hours 0-24, and so on. It is primarily useful for astronomical or metaphysical calculations. A degree is really just a division of any arbitrary whole unit, and especially a looping unit, such as the circle, whose end leads back into its beginning. Because of this, you can measure the year in radians, or the apparent sky in solar days. Occasionally this proves to be useful: midnight corresponds to Winter, 6 AM to Spring, 12 PM to Summer, and 6 PM to Autumn. I think we would all agree that the harshness of noon is exactly like that of Summer, and that the relief of the evening is quite similar to the relief of the cooler Autumn. These observations are called metaphysical correlations; the observations that, in a regular fashion, the effects of one cycle's phase nearly mirror those of another at the same phase, albeit on a different scale or applied to a different aspect. Degree systems are very useful in these cases, as they allow us to regularly correlate the phases of various cycles in the same, well-understood unit. Musical intervals are conceptualised such that a TET scale is drawn as a set of equidistant points on a circle. This means that the root and tritone are on opposing ends of a circle, NOT the root and fifth as it would be if a linear scale was drawn this way. So, the other degree systems are considered logarithmically spaced when converted to musical intervals (0.5 turns = 1:sqrt(2), for example). This is the same system as is used to draw musical scaled in AudioKit Synth One and some other popular synthesizers.
