Is a vernier scale accurate or precise?
Precision refers to the repeatability of the instrument and also the smallest value of the parameter (in this case length or thickness for example) that can be measured. A properly calibrated vernier scale (or vernier calipers) is both accurate and precise. Accuracy refers to the zero error if any.

The vernier has ten spaces between the vertical spaces, so, the instrument divides by ten the millimeter, the smaller division of the main scale, obtaining the tenth of millimeter 0.1mm.
What is the difference between the main scale and the vernier scale?
Therefore, the main scale reading depends on the vernier scale, while the vernier scale reading depends on the aligned line. What is the aligned line? Whenever you slide the vernier scale, there must be two lines (one from the main scale and one from the vernier scale) that completely shape a united straight line.
What is the resolution of a Vernier caliper?
When it comes to metric vernier caliper, there are several resolutions available: 0.02 mm, 0.05 mm, and 0.1 mm. Different resolution has different graduation model. Soon, you will know the graduation models that we mean and how to read them.

What is the main scale reading?
The main scale reading is the amount of the vernier scale divisions that are completely passed by the vernier scale’s zero line. While the vernier scale reading is the amount of vernier scale divisions from 0 to the aligned line.

How to read a Vernier caliper?
How to Read a Vernier (caliper) Looking at an early caliper, you'll notice that it kinda looks like a tomahawk and has a scale down it's length. More about the scale later. On the bottom left, the "blade of the hatchet" are the jaws of the caliper for measuring outside dimensions - think of a tube. This would measure the outside diameter.
Which is simpler, the imperial or the metric?
Metric system is far simpler than Imperial system. You just move the decimal point forward or backwards to get you measurements. Add or take a zero. 30g=300mg, etc.
How to hold a caliper?
This is the proper way to hold a caliper. Use your thumb to slide the jaws open and closed. Yup, another tool that was totally designed for righties. Use the locking screw at the top if you want to set a dimension on the caliper and then check parts against your setting.

Does Home Depot have metric scale?
I just got one from Home Depot, it has both metric and standard readings, though the standard looks to be in fractions, not decimals, so I have next to no clue how to read it properly. The metric side, however, is easy to understand after your instructions (converting them to fit the metric scale, of course).
What is a Vernier scale?
The vernier scale was invented by French mathematician Pierre Vernier in 1631 as an upgrade on Pedro Nunes' measurement system for precision astrolobes. With a main scale and a sliding secondary scale, a vernier is used for making precise measurements.
How does the Vernier scale work?
How a Vernier Scale Works. The vernier scale is marked with divisions slightly smaller than the divisions of the main scale. For example, a vernier scale could have 11 markings for every 10 on the main scale. That's 10 divisions on the vernier scale for every 9 on the main scale. This means that the vernier divisions are each 90% ...
How to read a micromanipulator?
On this micromanipulator, the linear scale is read first. Whole numbers are shown on the top of the linear scale and half numbers are shown on the bottom. In the first image, we see a measurement of 5.0mm. Then we read the rotational scale, which has 50 increments. For this instrument, two complete revolutions of the rotational scale equals 1.0mm mark on the linear scale. That means that each mark on the rotational dial is equivalent to 1/100th of a millimeter. For the example at the right, the 0 mark on the rotational scale lines up exactly with the center line of the linear scale. Therefore, the reading is exactly 5.00mm.
What is the half mark on the linear scale?
On the linear scale, the 5 is visible, and you can see the half mark (0.5 ) on the bottom side of the linear scale. Since the rotational scale is exactly at 0, the final measurement is 5.50mm. In the last example (right), 6.5 is visible on the linear scale.
Is the Vernier scale rotational?
On some of instruments, the vernier scale is rotational, like the circular one on the M325 micromanipulator that is shown below.
How to read a Vernier scale?
The vernier scale on a caliper is attached to the sliding jaw and moves along the main scale. The inch vernier scale has 25 divisions in the same length that the main scale has 24 divisions. The difference between a main scale division and a vernier division is 1/25 of a main scale division. 1/25 of 0.025 in. equals 0.001 in. or 1 mil, which is the discrimination of the instrument or the least count. You read a vernier instrument or the controls on machines by adding the total readings on the vernier scale. Remember, only when the vernier is at zero do two lines, 0 and 25, of the vernier scale coincide with the main scale.
Why is a Vernier scale mounted?
Scales are mounted so that you can make readings from one scale to the other with a minimum parallax error.
What instruments use Vernier calipers?
Nowadays, vernier instruments also include height gages, depth gages, gear tooth instruments, and protractors. These simple scale instruments all use verniers to increase their amplification, which, in turn, increase their discrimination. Adding verniers to instruments that use other means of amplification, such as micrometers, increases their precision.
Can you use a vernier scale in decimal?
For example, we can use a vernier scale and a main scale in decimal-inches-the vernier has been a decimal instrument from its inception. Each inch is divided into 10 parts, and each division is subdivided into quarters, making the smallest division 1/40 in., or 0.025in., read as 25 mil.
What is the Vernier scale?
The vernier scale is a technological device that increases the sensitivity of a scale to subdivide the lower division of it. In this simulator the vernier scale (rectangle below the scale) has eight spaces between the vertical lines. It divides by eight the 1/16in, which is the smallest division of the main scale (1/16in / 8 = 1/128in).
How many divisions does a Vernier scaler have?
The vernier scaler has eight divisions. He divides the smallest division of the main scale for eight (1/16in / 8 = 1/128in) -figure 2. figure 2 – Vernier – to divide by eight smaller division of the main scale. The mark of the vernier which align with a mark of main scale indicate the (sub)division of the measure -figure 3.
What does the mark of the Vernier align with?
The mark of the vernier which align with a mark of main scale indicate the (sub)division of the measure -figure 3.
What happens if the zero of the Vernier does not coincide with a mark of the main scale?
If the zero of the vernier does not coincide with a mark of main scale (is between two), the main scale: some inches to the entire value of the fraction on the left of the zero mark of the vernier to the value of the vernier marks are aligned (phew). In the example of figure 3.
