Usage in Medicine
In medicine, a ruler is often used to measure the size of wounds, lesions, or other physical features of the body. This can be important in diagnosing conditions, tracking the progress of a disease, or planning surgical procedures. For example, a ruler might be used to measure the size of a tumor before and after treatment, to determine whether the treatment is working.
