Field of view at 1,000 m
In the technical data the field of view is always given for one thousand meters, e.g. 56 m/1,000 m. This means that from a distance of one thousand metres, the field of view is 56 metres wide. This information is sometimes also specified in degrees. With these conversion formulas, you can calculate the information yourself. The factor 17.5 means the visual field in meters with a field of view of 1°.
Field of view at 1,000 m = degrees (true) x 17.5
Degrees (true) = field of view at 1,000 m / 17.5
