How do you read a metric micrometre?
To read the metric micrometer, first read the number of whole millimeters on the bottom row of the sleeve of the micrometer (Figure 3). These are the whole millimeters. If there is an additional line uncovered on the top row, this is equal to one-half a millimeter (Figure 3).
What is the vernier scale on a micrometer?
The vernier scale of a metric micrometer has a measuring range of 0.01mm and is graduated in 10 increments. Each increment represents 0.001mm. The reading on the vernier scale is the value that aligns best with any increment on the thimble scale (0.009mm in the image on the left).

How to Read a Linear Vernier Scale
- 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 use a micrometer?
Grasp the thimble between your thumb and index fingers. Place the C-shape of the frame against your palm. Finally, partially wrap your pinky or ring finger within the inside of the frame. Hold the object to be measured in your non dominant hand.
How do you read a vernier caliper and micrometer screw gauge?
The main scale reading is the first reading on the main scale immediately to the left of the zero of the vernier scale (3 mm), while the vernier scale reading is the mark on the vernier scale which exactly coincides with a mark on the main scale (0.7 mm). The reading is therefore 3.7 mm.
How do you read a micrometer reading?
To read the micrometer in thousandths, multiply the number of vertical divisions visible on the sleeve by 0.025″, and to this add the number of thousandths indicated by the line on the thimble which best coincides with the central long line on the sleeve.
