K or f/i is the stadia interval factor of the instrument If one observes a vertical length on a stadia rod, rule or levelling rod with the telescope and sees that the rod spans 0.500m between the marks (the stadia interval), then the horizontal distance from the instrument to the rod is: In the adjacent image, the upper stadia mark is at 1.500m and the lower at 1.345m. The difference is 0.155m. Thus the distance from the instrument to the levelling rod is: Rangefinding crosshairs in a surveying instrument, D is distance from the telescope to the rod, S is the difference between the rod readings at the two stadia marks.
