Final answer:
The millimeter (mm) is used to measure small objects requiring high precision, such as a seed or staple. For larger objects like textbooks or tables, centimeters (cm) are a more appropriate unit of measurement. Millimeters are not typically used as one of the five sizes in digital design.
Step-by-step explanation:
Of the various units used in digital design, the millimeter (mm) is not one of the five sizes typically used. In digital design, the selection of measurement units is crucial to ensuring the accuracy and scalability of the objects being designed. When considering what to measure with a millimeter, we focus on objects that are small in size, such as seeds or staples.
A millimeter is the smallest commonly used unit in the metric system and is appropriate for measuring objects that require a high degree of precision. For larger objects, such as a piece of paper or a textbook, centimeters would be the better choice as they are the most appropriate unit to capture the dimensions of these objects without unnecessary precision. For example, when David is measuring his textbook to complete a project, he would use centimers as the unit of choice since the book is much larger than the tiny objects best suited to millimeter measurements.
In the context of measuring larger objects, where one needs a balance between precision and practicality, centimeters, which have 10 millimeters in each, are used rather than millimeters. Millimeters provide precision but can be impractical for everyday objects that do not require extreme detail. Hence, in situations like measuring the width of a table or the length of a paper clip, millimeters are the more appropriate size to get an accurate measurement which is closer to the actual size.
