14 Things That Are 5 Millimeters (mm) Thick

The term millimeters refers to the sizes of small objects, including parts of the human body.

Understanding measurements goes a long way in helping you get the right tools for the job. For example, doctors use millimeters in hospitals to determine tumor sizes and settle on a treatment method. Therefore, it is necessary for everyone to at least learn about measurements and reference points.

For instance, 5 mm is a common unit of measurement in construction and electrical work. You can easily use the thickness size to pick the right tools for a job.

The list below will cover a few items that are 5 mm thick to help you compare objects around you.
