Seven divisions are not seven hundredths
Suppose a club is writing a size note for a removable label tab on an FPV storage pouch. The invented reading below is only a transcription exercise for that noncritical accessory, not a measurement of an actual tab or a specification for making one.
Read the zero first, then the matching line
The assumed 0.05 mm vernier zero has passed 12 mm, but not 13 mm. Its seventh line matches a main-scale line: use 12 mm plus seven increments of 0.05 mm.
12 mm+ (7 × 0.05 mm)= 12.35 mm
In this scale design, adjacent vernier lines are 0.95 mm apart: 12.35 + 7 × 0.95 = 19 mm. Physical spacing differs from the 0.05 mm reading increment; 19 is not the main-scale contribution.
Practice entry: “Pouch label tab — hypothetical reading 12.35 mm; 0.05 mm vernier.” Do not remove “hypothetical” and reuse it as a measured dimension.
