VERNIER CALIPER LAB

Interactive Realistic Vernier Caliper Simulation & Reading Practice

Drag the slider jaws directly on the canvas or use the controls below.

Controls

Jaw Separation Distance 0.00 cm

Measurement Breakdown LC = 0.01 cm

Main Scale Reading (MSR): 0.0 cm
Vernier Coincidence (VSD): 0 division
Vernier Scale Reading (VSR): 0.00 cm
Zero Correction (ZC): 0.00 cm
Corrected Reading: 0.00 cm

Formulas & Practical Notes

1. Least Count (LC)

$$\text{Least Count} = 1\text{ MSD} - 1\text{ VSD} = 0.1\text{ cm} - 0.09\text{ cm} = 0.01\text{ cm}$$

2. Total Observed Reading

$$\text{Observed Reading} = \text{MSR} + (\text{VSD} \times \text{LC})$$
