How the least count of vernier calipers can be found?

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. Note: Least count can also be calculated by taking the difference of one main scale division and one Vernier scale division.

The least count of vernier callipers is also known as the vernier constant. It is defined as The difference between one main scale division and one vernier scale division. Therefore, the least count of vernier calliper is 0.1 mm.

For Micrometer there are 50 divisions on the circular scale and minimum division on the main scale counts 0.5mm. We can calculate by the above formula L.C = 0.5/50 = 0.01mm.

Zero Error

1. Smallest reading on the main scale = 1mm.
2. Number of divisions on man scale = 10.
3. Least count of the main scale = 0.1 mm.
4. The secondary scale is the vernier scale.
5. No. of divisions on the secondary scale = 10.
6. Instrument least count = 0.01 mm.

Vernier caliper’s Least count = the smallest reading within main scale/ Number of divisions within vernier scale = 1 mm ÷ 10 divisions = 0.1 mm.

Answer: Micrometer least count is 0.01 mm.

The least count is the smallest measure that a instrument can measure. micrometer may have a least count of 0.01 mm or 10 microns and thus it can measure better than a measuring ruler or a slide caliper. Micrometer least count is 0.01 mm.

1. The least count is the minimum unit measurement, which can measure from the scale (device) with high accuracy.
2. The least count of the meter scale is 1 m m .

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.

Zero error =1−(v⋅c⋅D× least count )

Least Count: 0.01mm.

= 0.1 cm and The least count is 0.05 mm.

The least count of a vernier calliper is 0.01 cm And its zero error is – 0.03 cm. While measuring the length of a rod, the main scale reading is 4.6 cm and 8^Th Division on vernier scale is in line with a marking on the main scale. Calculate the length of the rod. A.

Least count of a vernier callipers is 0. 01cm. When the two jaws of the instrument touch each other the 5th division of the vernier scale coincide with a main scale division and the zero of the vernier scale lies to the left of the zero of the main scale.

Caliper is A linear measuring instrument with a scale and a cursor that slides on it. It is designed to take external linear measurements by contact. It can also measure internal dimensions, depths, bumps, among others.

The least count (LC) is given by LC = 1 MSD – 1 VSD = 1.0 – 0.9 = 0.1 mm. Given, the main scale reading (MSR) is 10 and the Vernier scale reading (VSR) is 1. The measured value of the edge is given by A=MSR+VSR×LC=10+1×0.1=10.1mm.

The circular scale has been divided into 100 parts. When we rotate this whole round, then it goes 1 mm forward or backward. It means it’s the least number of counts 100 mm of 1 mm or 1/100 means 0.01 mm. least count = 1 /100 = 0.01 mm.

Least count of a vernier calliper is 0.01 cm.
