No unit for vernier scale coincidence. But as we multiply it by least count which has unit then we get vernier scale reading with the same unit. Of course main scale reading and vernier scale reading would have the same unit
The zero error for a Vernier caliper is the systematic error that occurs when the jaws do not exactly close at zero. The reading uncertainty for a Vernier caliper typically depends on the precision of the scale divisions, with the main scale usually indicating whole millimeters and the Vernier scale providing readings to the nearest 0.02 mm.
The reading uncertainty for a vernier caliper is typically equal to half of the smallest division on the main scale. For example, if the smallest division on the main scale is 0.1 mm, the reading uncertainty would be 0.05 mm. This uncertainty represents the smallest increment that can be reliably measured with the vernier caliper.
First we keep the body in between the jaws of the caliper. Then we note the main scale reading and then vernier coincidence. Vernier coincidence is to be multiplied by the least count of the device. This is added with the main scale. That will be the required value of the dimensions of the object.
Yes, a vernier caliper can measure the inner diameter of a bore accurately. The lower jaws of the caliper can be inserted into the bore, and the reading can be taken from the scale and vernier to determine the diameter. It is important to ensure that the caliper is properly aligned and the jaws are perpendicular to the bore for an accurate measurement.

The main scale is before the zero line of the vernier scale.
The zero reading of a vernier caliper is when the jaws are closed and the main scale '0' mark aligns perfectly with the zero mark on the vernier scale. This is the reference point for taking measurements with the vernier caliper.

To measure the inside diameter of a ring using a vernier caliper, you can gently open the jaws of the caliper, place them inside the ring, and then slowly close the jaws until they fit snugly against the inner circumference of the ring. Take the reading from the main scale and vernier scale where they align. This will give you the inside diameter measurement of the ring.
To take a main scale reading, identify the whole number on the main scale that is to the left of the zero mark on the vernier scale. Then, identify the vernier scale division that aligns closely with a division on the main scale. Add the main scale reading and the vernier scale reading together to get the final measurement.
Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.
To take readings with a vernier caliper, first ensure the jaws are closed and check the zero reading for accuracy. Then, open the jaws to fit around the object you want to measure and close them gently until they make contact. Read the measurement by locating the main scale reading just before the zero of the vernier scale, then find the line on the vernier scale that aligns best with a line on the main scale. Add the two values together to get the final measurement.
