How many scales does a Vernier caliper have?

A Vernier caliper has two scales on it: one is marked the whole length of the caliper, the other is mounted on the jaw of the caliper that moves. The two scales have fine markings on them that have slightly different distances between the markings. For instance, the scale on the whole length of the caliper may be marked with 10 marks/cm, while the scale on the jaws marked with 10 marks/0.9 cm. Because the marks don’t line up exactly, it is possible to use them to get even greater precision than you could otherwise.
