This is just a little program I made in order to learn a bit of C++. It is used for converting pixels on a picture or drawning to degrees & milliradians to ease the process of making a HUD in DCS World. Note that this will work better the higher resolution the picture is.
- Open the .exe (or compile it yourself with the source code).
- Measure the reference distance in pixels. This distance should be known in degrees. Example picture is between the horizon line and -10° pitch line (10° difference):

- Input the pixel and degrees length of the reference distance.

- Measure the length of the distance you want to know the length of in degrees. Example picture is the length of the speedtape:

- Input that length.

- Result is displayed as follows (in this case the length of the speedtape is probably 5°):
