This reasonably good dial indicator has divisions of 0.001mm (about 1/20,000 inch). The big pointer makes one full revolution per 0.1mm, while the small pointer goes around once per 5mm. Over its 5mm (about ¼ inch) range, the main pointers turns fifty times. (Which means that when you push the rod in, the pointer spins fast!)
