An easy guide to how understand the Vernier caliper. A Vernier caliper gives measurements by centimeters (cm) and is accurate to 2 decimal points (E.g. 1.23 cm). The method for reading measurement explained in this post will be the same for Vernier calipers that output measurements in inches.
How to Use a Vernier Caliper?
It’s like a scale along its length. The scale will discussed in the future. To the left, on the bottom” the “blade of the hatchet” are jaws that the caliper uses used for measuring the dimensions outside Think of tubes. Its used to measure the outside diameter. Thats why the “pike” on top of the hatchet can used to determine the inside dimensions . Consider the inside diameter of a tube. Then, look all the way to the right.
To be able to comprehend the readings of measurement from a the vernier caliper correctly it is important to keep in mind two points before you begin. For instance, if the vernier caliper produces the measurement reading 2.13 centimeters which means:
- The Main scale provides the primary number(s) along with one decimal position to give the read (E.g. 2.1 cm, where 2 is the principal number, and 0.1 is the single decimal-place number)
- The vernier scale provides the second decimal point for the read (E.g. 0.03 cm)

1. If you have noticed it appears that “handle” of the caliper has a scale that begins at to zero left, and increases by 6 inches right on in this instance. Different calipers may be larger in length. The largest number at the middle of the scale represents the in number. In this instance, we’re taking a look at the space immediately following one inch marks to the left. After that, we will see 2 on the right.
2. on the right hand side, which is the number for the second inch. Its evident that every inch can divided into equal parts, with the numbers 1 to 9. This makes each of these lengths 1/10 of an inch (0.100). Then, each space between each inch has three lines which break each 1/10 an inch into four equal pieces. Each of these tiny pieces is therefore twenty-five thousandths (0.025) in length.

3. A scale can also seen at the right side of the photo. It starts at zero. there’s a 5 and a 10, and a 15. It gets up to 25, however the image doesn’t reveal the actual number. This is the more extreme part of the caliper. Note that the line for the number 0 (zero) is located to just to the right line that follows the number 3.
4. We know that there’s a big number 1 on right of this image, which we don’t have (which means 1 entire inch) Let’s write that in (1.) and then we’ll add the decimal mark in. The 3 left of the zero line on the vernier, therefore we’ll include that in the number (1.3). The zero line lies to the right, on the second line that follows the 3. There are at most fifty trillionths of it (0.050) however there’s more.
5. Note how the zero line is only one smidge to the left of the second line following the. Then look at the larger 2 and note how the Vernier line on 13 is on the left. Therefore, the problem is to determine which line on the Vernier coincide precisely with the size at the center. In this particular case it appears like۔
