A digital (or electronic) caliper is a precision instrument used to take very accurate measurements. Measurements can be clearly read from the caliper's LCD display. The LCD screen takes the place of the dial indicator of the dial caliper and the vernier scale of the vernier caliper, and makes the digital caliper much easier to use. Most are able to measure up to 0.01 mm (0.0005 inches). Digital calipers can take measurements in both metric and imperial units.
