How to read the vernier
Step 1. Read the main-scale cm mark to the left of the vernier zero.
Step 2. Find the vernier division that lines up exactly with a main-scale tick.
Step 3. Multiply that number by 0·01 cm and add it to step 1.

How to read the micrometer
Step 1. Read the whole mm on the sleeve (below the datum line).
Step 2. Check if a half-mm mark is visible (above the line). Add 0·50 mm if so.
Step 3. Read the thimble where the datum line crosses it, × 0·01 mm.
