Continue reading Difference between ULM and CMM MachineLeast count is the smallest value any instrument can read or measure. You may hear of vernier caliper of least count 0.02 mm, which means the minimum value vernier can measure is 0.02 mm.
You can’t measure a value less than 0.02 mm with this vernier calliper.
The same thing applied to all other instruments, a usual scale of least count of 1 mm, can measure a minimum length of 1 mm only.
Vernier Caliper is a widely used linear measurement instrument with the least count of 0.02 mm. It is used to measure linear dimensions like length, diameter, and depth.
Let’s discuss common Mechanical measuring instruments with their least count (Considering least count of commonly used instruments, you may find changes in special cases)
Instruments | Least count |
---|---|
Vernier Caliper | 0.02 mm |
Digital Caliper | 0.01 mm |
Outsite Micrometre | 0.01 mm |
Vernier Micrometre | 0.001 mm |
Digital Micrometre | 0.001 mm |
Vernier Depth gauge | 0.02 mm |
Vernier Height Gauge | 0.02 mm |
Electronic Height Gauge | 0.001 or 0.0001 mm |
Glass scale | 0.1 mm |
