Each tenth of an inch is further subdivded into four increments, each of which is 0.025 inches long. |

The vernier scale of an imperial caliper has a measuring range of 0.025 inches, and is graduated in 25 increments.
Therefore, each increment is equal to 0.001 inches (0.025 ÷ 25 = 0.001). This is the resolution of the caliper. |
