This tool is a(n) __________.
outside caliper |
|
micrometer |
|
vernier caliper |
|
inside caliper |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
Measuring tools provide a convenient and easy way to compare object dimensions against:
perfection |
|
a standard |
|
each other |
|
a drawing |
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
