What is another word for vernier?
Pronunciation: [vˈɜːnɪə] (IPA) 
Vernier is a term used in metrology and engineering to describe a type of scale used to measure small distances. Some synonyms for vernier include gauge, calliper, micrometer, and caliper rule. These tools are used to accurately measure objects and spaces within a thousandth of an inch or even less. While the vernier scale uses a sliding component to increase accuracy, the micrometer or caliper rule is a more traditional tool based on a calibrated screw. In general, these tools serve the same basic purpose, providing a precise measurement of size or distance. Whether it's for manufacturing or scientific research, precision measuring instruments like these are crucial for accurate results.
