- Read the main scale. Look for the last whole increment visible before the 0 (zero) mark.
- Read the secondary scale (Vernier) measurement. This is the division tick mark that lines up best with a mark on the main scale.
- Add the two measurements together.
How do you read vernier calipers mm and inches?
A Vernier Caliper To read a vernier caliper:Read the large number division first.Read the small number division.Read the number of smaller subdivisions. Each represents 0.025 inches to be added to the measurement.Read which line on the vernier lines up with a line on the main beam.
How do you read a vernier caliper 0.05 mm?
Each numbered line on the bottom scale is 0.1mm extra, each unnumbered line is 0.05mm extra. The closest matching line is the amount to add. Look along the scale until you find the first place where a numbered line on the bottom scale aligns to a line on the top scale.
How do you read vernier caliper inches and centimeters?
Measurement Reading Technique For Vernier Caliper The main scale contributes the main number(s) and one decimal place to the reading (E.g. 2.1 cm, whereby 2 is the main number and 0.1 is the one decimal place number) The vernier scale contributes the second decimal place to the reading (E.g. 0.03 cm)
What is the value of 1 vernier scale?
The number of divisions on the vernier scale, in general, is 10 divisions. Therefore, the number of divisions on the main scale is given as n-1 = 10 – 1 = 9, which is equal to 9 mm. Therefore, we can say that each division on the vernier scale is equal to 1/10 mm.

Is vernier in cm or mm?
The vernier scale consists of a fixed metric scale and a sliding vernier scale. The fixed scale is divided into centimeters and millimeters, while the vernier scale is divided so that 50 divisions on it cover the same interval as 49 divisions on the main scale.
Is vernier scale in cm or mm?
1, the smallest measurement on the main scale is 0.1 cm or 1 mm. The vernier scale can read to 0.05 mm. So using both scales, the width can be read to the nearest 0.005 cm (or 0.05 mm).

How to read a Vernier caliper?
In order to read the measurement readings from vernier caliper properly, you need to remember two things before we start. For example, if a vernier caliper output a measurement reading of 2.13 cm, this means that: 1 The main scale contributes the main number (s) and one decimal place to the reading (E.g. 2.1 cm, whereby 2 is the main number and 0.1 is the one decimal place number) 2 The vernier scale contributes the second decimal place to the reading (E.g. 0.03 cm)
Where is the main scale reading on the Vernier scale?
The main scale reading is obtained from the reading on the main scale that is at the immediate left of the zero on the vernier scale.
What is the main scale?
The main scale contributes the main number (s) and one decimal place to the reading (E.g. 2.1 cm, whereby 2 is the main number and 0.1 is the one decimal place number)
What is the reading on the top of a measurement?
The reading on the top is the measurement obtained and the reading at the bottom is the zero error. Find the actual measurement. (Meaning: get rid of the zero error in the measurement or take into account the zero error)
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.
How many divisions per cm on a Vernier caliper?
This model has 10 divisions per cm on its main scale and 50 divisions on its vernier scale. Example of vernier caliper that comes with this graduation model is Mitutoyo 532-119 vernier caliper.
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 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 many divisions does the Vernier 0 mark pass?
You could see the following picture. The first (left) yellowed line shows how many divisions passed by the vernier 0 marking. In this case, it has passed 42 divisions. While the second (right) yellowed line shows the aligned line.
What happens if you don't read Vernier caliper?
This is the core thing when you read vernier caliper. It requires good eyesight. If you fail to do that , your measurement will be incorrect.
How many divisions per inch is a graduation model?
This model has 50 divisions per inch on its main scale and 20 divisions on its vernier scale. Example of vernier caliper that comes with this graduation model is Starrett 456AZ.
How to read Vernier scale?
Read the Vernier scale. Find the first mark on the Vernier scale that lines up perfectly with any line on the main scale. That mark tells you the value of the additional digits.
What is the difference between a sliding scale and a Vernier caliper?
The main scale is "life size," while the sliding scale is magnified for easy reading. This magnification system allows the Vernier caliper to measure more precisely than a ruler. Check the scale of your smallest divisions. Before making a measurement, count the number of lines between two numbers on your Vernier scale.
What does each numbered division on the Vernier scale represent?
If the sliding scale doesn't have a label, you can assume the numbered divisions represent 1/10 of the smallest division on the main scale . For example, if the main scale's smallest lines represent 0.1 inches, then each numbered division on the Vernier scale represents 0.01 inches.
What is a Vernier caliper?
A Vernier caliper is an instrument that measures internal or external dimensions and distances. It allows you to take more precise measurements than you could with regular rulers. This wikiHow will show you how to use and read a Vernier caliper. Steps.
How to measure length?
For measuring length, compare the 0 line of the Vernier scale with the main scale. Then check the division that coincides with the main scale. Then add the first reading with the third reading by multiplying.
How many lines are there on a Vernier scale?
For example, the numbers on a Vernier scale represent 0.1 inches, and there are five unnumbered lines between them. 0.1 inches ÷ 5 = 0.02 inches, so each of the unnumbered lines represents 0.02 inches.
What is the zero error on a sliding scale?
If the zero on the sliding scale is to the left of the main scale zero, you have a negative zero error. Slide it so the zeros line up, while watching another mark to see the size of the error. For example, if the 0.5mm mark moves from the 1mm mark to about the 2.1 mm position, the zero error is - (2.1 - 1), or -1.1 mm. Add 1.1 mm to all measurements to correct this.
How accurate is a Vernier caliper?
Reading the measurement on a Vernier caliper can be tricky. However, it can measure to the accuracy of one-thousandth of an inch (up to 2 decimal places). A Vernier caliper has two rulers: the main scale and the sliding Vernier scale. Reading the caliper is a two-step process:
Why use Vernier Calipers?
Vernier calipers have both a fixed main scale and a moving vernier scale. The main scale is graduated in either millimetres or tenths of an inch. The vernier scale allows much more precise readings to be taken (usually to the nearest 0.02mm or 0.001 inch) in comparison to a standard ruler (which only measures to the nearest 1mm or 0.25 inch).
How many graduations are there on the Vernier scale?
The Vernier scale is located on the sliding jaw and typically has 25 graduations. The scale contributes to the second decimal place in the reading and represents a thousandth of an inch (0.001), with each .005 inch numbered successively as 0, 5, 10, 15, 20, and 25.
What is the nearest vernier scale?
The vernier scale allows much more precise readings to be taken (usually to the nearest 0.02mm or 0.001 inch) in comparison to a standard ruler (which only measures to the nearest 1mm or 0.25 inch).
What is the measurement of a sliding scale?
For example, if the 0 on the sliding scale lines up with the 2 inch mark, your measurement is 2 inches. If it lines up past 2 inches by six tenth-inch marks, your measurement is 2.6 inches.
Where to read large number division?
Read the large number division first from the main scale to the left of the “zero” of the Vernier scale.
What is scale in calipers?
Scale: Runs along the beam of the caliper. This gives you the measurement reading.
