What is the Difference Between Vernier Caliper and Micrometer Screw Gauge?
🆚 Go to Comparative Table 🆚The main differences between a vernier caliper and a micrometer screw gauge are their measurement range, accuracy, resolution, and application. Here's a comparison of the two instruments:
- Measurement Range:
- Vernier Caliper: Has a broader measurement range, often covering several inches or centimeters. It can measure from 0 to 150 mm or more, depending on the caliper's design.
- Micrometer Screw Gauge: Typically has a more limited measurement range, and is used for measuring smaller dimensions.
- Accuracy and Resolution:
- Vernier Caliper: Less precise compared to micrometers but still offers good accuracy. It typically has a resolution of 0.02 mm or 0.001 inch.
- Micrometer Screw Gauge: Offers higher precision and resolution compared to vernier calipers. It can provide measurements with resolutions as fine as 0.01 mm or even 0.001 mm.
- Application:
- Vernier Caliper: Measures the dimensions of objects, both internal and external, using two sets of jaws. It can measure lengths, diameters, and depths.
- Micrometer Screw Gauge: Measures the distance between two opposing flat surfaces using a threaded spindle and anvil to capture and measure the thickness or diameter of an object.
- Measurable Dimensions:
- Vernier Caliper: Can be used for both internal and external types of measurement.
- Micrometer Screw Gauge: Can only be used for external measurement and cannot measure internal dimensions.
In summary, micrometers excel in precision measurements of small objects, while vernier calipers offer a broader range of measurement for both internal and external dimensions.

Here is a table comparing the differences between a Vernier caliper and a Micrometer screw gauge:
Feature | Vernier Caliper | Micrometer Screw Gauge |
---|---|---|
Accuracy | Less accurate than a micrometer, but still precise | More accurate than a Vernier caliper |
Measurement Range | Wide range of measurement | Limited range of measurement (typically up to 25 mm) |
Application | Versatile and used in a wide range of applications, including metalworking, woodworking, and general mechanical work | Often used in precision machining, engineering, and manufacturing where extremely accurate measurements are required |
Operation | Measures dimensions of objects using two sets of jaws (internal and external) and a sliding Vernier scale | Measures the distance between two opposing flat surfaces using a threaded spindle and anvil |
Digital Availability | Available in digital form for increased accuracy and precision | Available in digital form for increased accuracy and precision |
Both Vernier calipers and micrometer screw gauges are widely used in various industries for precision measurements. While Vernier calipers are more versatile and have a wider range of measurement, micrometers excel in precision measurements of small objects.
