What measurement capability describes a vernier caliper?

• A. Measures mass
• B. Measures inside and outside dimensions and depth
• C. Measures temperature
• D. Measures pressure

Answer: (B)

Vernier calipers are designed to measure three common dimensions with precision: outside dimensions across the jaws, inside dimensions between the jaws, and depth using a rod that extends from the end. The tool’s external jaws grip the outside edges of a part to get its external size, the smaller internal jaws fit inside holes or slots to capture internal dimensions, and the depth rod measures how deep a hole or recess is. The vernier scale lets you read fractions of the smallest main-scale division, giving more precise measurements than the main scale alone. Because of these capabilities, this tool is described as measuring outside and inside dimensions and depth. It isn’t used for mass, temperature, or pressure, which require different instruments.
