Which tool would you use to make precise measurements of small objects?

A micrometer is the appropriate tool for making precise measurements of small objects because it is specifically designed to measure small distances with high accuracy. It typically has a screw mechanism that allows for fine adjustments, enabling users to measure objects down to the thousandth of a millimeter. This makes it ideal for tasks requiring extreme precision, such as in mechanical engineering or machining.

In contrast, a sliding bevel is used primarily for transferring angles and is not intended for measuring small dimensions accurately. A carpenter’s level is utilized to determine horizontal or vertical alignment, and it does not provide measurements of small objects. A keyhole saw is a cutting tool used for making intricate cuts in wood or other materials, not for measurement. Each of these other tools serves a different purpose and lacks the precision that a micrometer provides for small measurements.
