Nine millimeters- a measure of length or distance, just about equal to the thickness of a standard pencil. It is also a common caliber for a handgun cartridge.
A pencil's length is quite a bit more than either; a pencil's diameter is several millimeters, but less than a centimeter (unless you're talking about an oversized novelty pencil, or the kind that they make kindergarten students use).
The length of a standard pencil is typically around 7.5 inches in the imperial measurement system. However, pencil lengths can vary slightly depending on the manufacturer and design, with some being shorter or longer. Generally, this size is considered standard for most writing and drawing pencils.
Objects that are approximately four millimeters in size include a standard pencil eraser, a small pea, a sesame seed, and the diameter of a standard paperclip. These objects are commonly used as reference points for understanding the scale of four millimeters in everyday life.
