When converting degrees to mils, which factor is used for the conversion?

The correct factor for converting degrees to mils is 17.5. In the context of military applications, where precision in field artillery and navigation is crucial, the conversion relates to the fact that one complete circle is 360 degrees, while in mils, a circle comprises 6400 mils. Thus, to convert degrees to mils, you can use the factor of 17.5. This is derived from the equation:

1 degree = 17.5 mils.

When using this conversion, multiplying the number of degrees by 17.5 will yield the equivalent in mils. This conversion is particularly vital for artillery calculations where angles must be converted for accurate targeting and firing solutions.

In comparing the other factors, while 17.8, 4.20, and 15 are presented, they do not align with the widely accepted standard conversion used in military contexts, making 17.5 the most suitable choice.
