## Calculate the least count of the screw gauge.

The least count of screw gauges is 0.01mm.

To calculate the least count of a screw gauge, you need to use the following formula:

Least Count = Pitch of the Screw / Number of Divisions on the Circular Scale

The pitch of the screw refers to the distance traveled by the spindle in one complete rotation. It is usually provided by the manufacturer and is expressed in millimeters (mm) or fractions of a millimeter.

For example, let’s say the pitch of the screw is 1 mm and the number of divisions on the circular scale is 100. Plugging these values into the formula:

Least Count = 1 mm / 100 = 0.01 mm

Therefore, the least count of this screw gauge would be 0.01 mm.

**Step 1: Given data**

The least count of a screw gauge can be calculated using the following formula:

Least Count = Pitch / Total number of divisions on the circular scale

Given data:

- Pitch: [Provide the value of the pitch in millimeters (mm)]
- Total number of divisions on the circular scale: [Provide the total number of divisions on the circular scale]

**Step 2: Formula used**

The formula used to calculate the least count of a screw gauge is:

Least Count = Pitch / Total number of divisions on the circular scale

**Step 3: Calculation**

Substitute the given values into the formula:

Least Count = [Pitch] / [Total number of divisions on the circular scale]

Perform the calculation to determine the least count.

For example, if the pitch is 0.5 mm and the total number of divisions on the circular scale is 100:

Least Count = 0.5 mm / 100 = 0.005 mm

Therefore, the least count of this screw gauge would be 0.005 mm.

It is important to note that the least count may vary for different screw gauge models based on their specifications. Always refer to the manufacturer’s instructions or specifications for the precise values of the pitch and number of divisions on the circular scale to calculate the accurate least count of your specific screw gauge.
