use of the vernier caliper is to measure the internal and external diameters of an object. The word cal. ure objects which are smaller than 1mm but a vernier caliper can measure objects up to 1mm. As already know that vernier caliper has two scales the main scale and t.

Typically, measurements in the range of 0.010" or 0.2 mm require precision measuring instruments. refers to the degree to which a measuring instrument divides the basic unit of length it is using for measurement.
How you can work out the actual size from a measurement on a scale diagram. If the scale of the plan is 1 : 100, this means the real measurements are 100 times longer than they are on the plan. Try these ... You teacher will give you some plans to work on. Measure the lengths and complete each table.

Map or photo scale can be stated in one of two expressions as applied to aerial mapping: representative fraction or engineers’ scale. 6.1.1 Representative Fraction
Practice using the vernier caliper by measuring the length, inner diameter and outer diameter of the plastic pipe provided. Check your measurements with your lab partner; if there is disagreement, read the vernier scale again.
