Vernier Calliper Stainless Steel

Vernier Caliper Least Count

The least count of a vernier caliper is the smallest measurement that the instrument can make. It is determined by the difference between one main scale division and one vernier scale division.

The main scale is the long scale on the vernier caliper. It is divided into equal divisions, typically millimeters or inches. The vernier scale is a shorter scale that is placed alongside the main scale. It has the same number of divisions as the main scale, but the divisions are slightly smaller.

To find the least count, you can use the following formula:

Least count = (Main scale division) / (Number of vernier scale divisions)

For example, a vernier caliper with a main scale division of 1 mm and 20 vernier scale divisions will have a least count of 0.01 mm. This is because 1 divided by 20 is 0.05, so the smallest measurement that the instrument can make is 0.01 mm.

The least count of a vernier caliper can be as low as 0.01 mm, but it is typically between 0.02 mm and 0.05 mm. The higher the least count, the less precise the measurement.

Here are some examples of the least count of vernier calipers:

• 0.01 mm: This is a high-precision vernier caliper that is used for measuring small objects.
• 0.02 mm: This is a standard vernier caliper that is used for general-purpose measurements.
• 0.05 mm: This is a lower-precision vernier caliper that is used for less accurate measurements.

When choosing a vernier caliper, it is important to consider the least count that you need for your application. If you need to make precise measurements, then you will need a vernier caliper with a low least count. If you only need to make less accurate measurements, then you can use a vernier caliper with a higher least count.
