# What is the formula for least count of vernier scale?

## What is the formula for least count of vernier scale?

The formula of Vernier calliper least counts is determined by dividing the smallest reading of the main scale with the total number of vernier scale divisions. The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm.

### What is least count and write the formula?

The Vernier caliper least counts formula is calculated by dividing the smallest reading of the main scale with the total number of divisions of the vernier scale.LC of vernier caliper is the difference between one smallest reading of the main scale and one smallest reading of vernier scale which is 0.1 mm 0r 0.01 cm.

#### What is the formula to measure using vernier callipers?

Least count of a Vernier scale is calculated using the following formula, Least count = Smallest reading on main scaleNumber of divisions on Vernier scale=1mm10 = This is the least count for Vernier Callipers. Hence, the least count for Vernier Callipers is 0.1mm.

How do you calculate least count?

Mathematically a measurement instrument Least Count is calculated by dividing main scale reading by the total number of divisions on the main scale. And if the instrument also has a Secondary scale. Then instrument LC is the ratio of main scale L.C. and number of divisions on the secondary scale.

What is least count give example?

Definition: The smallest value up to which an instrument can measure is called least count of the instrument. Example: least count of meter rule is up to 1 mm. least count of Vernier caliper is 0.01 cm.

## How do you calculate the least count of spectrometer?

The entire circle is divided in to 360 degrees. Then, Least count = s – v = s – (59/60)s = (1/60) s = 1/60 degree = 1 minute. Hope this helps! Least count of Spectrometer is 1 minute.

### What is meant by least count?

Least count of a measuring instrument is the smallest measurement that can be made accurately with the given measuring instrument.

#### What is the least count of digital micrometer?

amiciTools 0.001 mm(least count) Electronic Micrometer 25 mm Screw Gauge Carbide Tipped Imperial/Metric System Digital Measuring Tool with Protective Case and Battery.

How do you calculate the least count of a micrometer?

Then the number of division on the circle scale will be 100 mm. Then it will be Lest count 0.01 mm. This is the Least Count (minimum count) of the micrometer. The low count = 0.5 / 50 or 1/100 = 0.01 mm or 0.001 cm.

What is the least count of vernier Spectrometer?

By using normal scale a minimum length of 1 mm can be measured. But least count of vernier is less than 1 mm.

## How do you find the least count of a Spherometer?

Procedure:

1. Find the pitch (p) of the screw and count the total number of divisions (N) in the circular scale.
2. Place the spherometer in the plane glass plate.
3. Place the spherometer on the convex surface.
4. Record the initial circular scale reading (r1) in table 3.1.
