Match each length measuring instrument listed on the left with its standard precision or suitable measurement application on the right.

Micrometer screw gaugePrecision of $0.01\text{ mm}$ ( $0.001\text{ cm}$ ); ideal for measuring small diameters like thin wires or paper thickness.
Vernier caliperPrecision of $0.01\text{ cm}$ ( $0.1\text{ mm}$ ); ideal for measuring internal and external diameters of small tubes.
Metre rulePrecision of $0.1\text{ cm}$ ( $1\text{ mm}$ ); ideal for standard laboratory lengths like simple pendulum strings.
Tape measureFlexible instrument ideal for measuring longer distances such as classroom dimensions.

Micrometer screw gauge matches with precision

0.01\text{ mm}

for fine wire diameter; Vernier caliper matches with precision

0.01\text{ cm}

for tube diameters; Metre rule matches with precision

0.1\text{ cm}

for laboratory lengths; Tape measure matches with flexible long-distance measuring.

Each instrument is correctly matched to its standard least count and characteristic physical measurement task: Micrometer screw gauge (

0.01\text{ mm}

), Vernier caliper (

0.01\text{ cm}

), Metre rule (

0.1\text{ cm}

), and Tape measure for long flexible lengths.

Identify the least count and primary application for each measuring tool.

Micrometer screw gauge:

0.01\text{ mm}

(wires); Vernier caliper:

0.01\text{ cm}

(internal/external tube diameters); Metre rule:

0.1\text{ cm}

(standard lab objects); Tape measure: large flexible distances.

Matching instruments requires recalling their resolution (least count) and physical design features.

Instrument least counts and appropriate selection based on object dimensions.
