What are the two main components of a Vernier caliper used to measure different types of diameters?
What are the two main components of a Vernier caliper used to measure different types of diameters?
Outside jaws for external diameters and inside jaws for internal diameters.
Describe the purpose of the Vernier scale on a Vernier caliper.
Describe the purpose of the Vernier scale on a Vernier caliper.
The Vernier scale provides a more precise reading than the main scale, allowing for measurements to be accurate to hundredths of a centimeter or thousandths of a millimeter.
Explain how to determine the final measurement using a Vernier caliper.
Explain how to determine the final measurement using a Vernier caliper.
The final measurement is obtained by adding the reading on the main scale to the reading on the Vernier scale.

Study Notes
Vernier Caliper
- The instrument has jaws for measuring internal and external diameters
- It has two scales: Main scale and Vernier scale
- The main scale is used to read centimeters (cm) or millimeters (mm)
- The Vernier scale allows readings to a higher precision, in hundredths or thousandths of a millimeter (0.01 mm or 0.001 mm)
Steps to use a Vernier Caliper
- Read the main scale value
- Read the Vernier scale value
- Add the main and Vernier scale values
- Convert the value to the required unit of length
Micrometer Screw Gauge
- This tool measures length with high accuracy
- The accuracy is typically to 0.001 cm or 0.01 mm
