It is less than a micrometer but greater than a non vernier caliper or ruler.
There are several conclusion for Vernier calipers. One is that in comparison to other tools like micrometers, they have less accuracy. Regardless, the Vernier calipers seem to allow a larger measurement range leading to better versatility.
To measure the internal diameter of a tube, you can use a caliper, such as a digital or vernier caliper, by placing the jaws inside the tube and reading the measurement where they touch the inner walls. Alternatively, you can use a small ruler or measuring tape, but this may be less accurate. Ensure the tube is clean and free of debris for an accurate reading. For precision, take multiple measurements at different points along the diameter to account for any irregularities.
The answer will depend on the scales. Bathroom scales usually have divisions of 1 or 0.5 kilograms and a similar minimum for mass. Precision scales will have divisions and minimum mass of less than a milligrams.
Each measuring tool has inherent limitations: a meter stick or ruler may have precision limited to millimeters, making it unsuitable for very fine measurements. A tape measure can be less accurate due to potential bending or stretching. Vernier calipers offer improved precision but can be prone to user error in reading the scale, while micrometer calipers, although highly precise, have a limited range and can be difficult to use on irregularly shaped objects. Additionally, environmental factors like temperature can affect the accuracy of these measurements.

Least count of vernier caliper= 1 MSD - 1 VSD. Main scale usually would have 1 mm as the minimum division. Such 9 divisions, ie 9 mm would be divided into ten equal parts in the vernier. So VSD = 0.9 mm Hence the least count = 1 - 0.9 = 0.1 mm If the same is to be given in centimetre, then it will be 0.01 cm.
A Vernier allows a precise reading of some value. In the figure to the right, the Vernier moves up and down to measure a position on the Scale. This could be part of a barometer which reads atmospheric pressure. The "pointer" is the line on the vernier labelled "0". Thus the measured position is almost exactly 756 in whatever units the scale is calibrated in. If you look closely you will see that the distance between the divisions on the vernier are not the same as the divisions on the scale. The 0 line on the vernier lines up at 756 on the scale, but the 10 line on the vernier lines up at 765 on the scale. Thus the distance between the divisions on the vernier are 90% of the distance between the divisions on the scale. If we do another reading with the vernier at a different position, the pointer, the line marked 0, may not line up exactly with one of the lines on the scale. Here the "pointer" lines up at approximately 756.5 on the scale. If you look you will see that only one line on the vernier lines up exactly with one of the lines on the scale, the 5 line. This means that our first guess was correct: the reading is 756.5. Here is a final example, with the vernier at yet another position. The pointer points to a value that is obviously greater than 756.5 and also less than 757.0. Looking for divisions on the vernier that match a division on the scale, the 7 line matches fairly closely. So the reading is about 756.7. In fact, the 7 line on the vernier appears to be a little bit above the corresponding line on the scale. The 8 line on the vernier is clearly somewhat below the corresponding line of the scale. So with sharp eyes one might report this reading as 756.73 ± 0.02. This "reading error" of ± 0.02 is probably the correct error of precision to specify for all measurements done with this apparatus. Now we shall use a simulation of a Vernier Caliper. A caliper measures a length, and in the following figure we show a caliper being used to measure the length of an Object. The Object will be placed between the "jaws" of the caliper. The Object is almost exactly 75 mm (2.95 in) long. In the above photograph, you can see that on the top of the caliper are two "prongs" which can be used to measure an interior dimension. There is also a piece of metal sticking out from the right side of the caliper, which is a depth gauge. Calipers commonly use a vernier scale. In the simulation below, you may "grab" the jaw of the caliper with the left button of the mouse and move it to some position. When you click on the Show button the distance between the jaws will be shown. Note that there is a small difference between the simulation and a real caliper: in the simulation the distance between the jaws is always an even multiple of a tenth of a millimeter. It does not allow readings between these values, for which we would have to estimate the value. The Java applet to simulate the vernier caliper was written by Fu-Kwan Hwang, Department of Physics, National Taiwan Normal Univ., and is used by permission. See related link for the applet.
The vernier scale provides a more precise measurement by showing how much the object has moved past a whole number on the main scale. Since 4 divisions of the vernier scale coincide with one less division on the main scale, each division on the vernier scale represents 1/4 of a division on the main scale. In this case, the total reading would be 35 main scale divisions plus 4 divisions on the vernier scale, giving a total of 35.25 divisions on the main scale. To find the radius of the cylinder, you would measure the circumference with a tape measure or string and then divide that measurement by 2π to find the radius.
the instrument can be made more sensitive by making vernier constant less ie by incresing the no of division on vernier scale or by decreasing the value of main scale.
Calibration of vernier calliper can be done using slip guages i.e. mirror finished rectangular blocks of alloy steel having different sizes & error less than one micrometer. These blocks can be joined together by sliding polished faces over each other to get disired length. Measuring this length & compairing the actual reading, we can calibrate the equipment.
Depends. The U.S. Army has divisions of 10,000 to 30,000. Other countries have divisions of less than 5,000.
You can and you will need a caliper rebuild kit. It is a lot easier to just replace the whole caliper though. I usually do. Takes lots less time and you dont have to worry about something not assembled right. Good luck.
A movement towards more unity, and less divisions.
