The unit that calculates PAIN is called a Visual Analog Scale (VAS) or a Numeric Rating Scale (NRS). These are tools used in clinical settings to measure and assess pain levels reported by patients.
There is no standardized SI unit for measuring pain. Pain is subjective and therefore difficult to quantify using a single unit of measurement. Instead, pain intensity is often assessed using scales such as the visual analog scale or numerical rating scale.
A numeric scale is appropriate because the patient/client can indicate, by pointing or raising fingers, to indicate his/her current pain level. Clients with motor aphasia cannot express themselves verbally or in writing.
The scale that determines how loud something is called the decibel scale. It measures the intensity of sound waves and allows us to quantify and compare the loudness of different sounds. The scale ranges from 0 dB (absolute silence) to around 120-130 dB (threshold of pain).
Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. In a clinical setting, pain is typically assessed using scales that measure intensity and quality, such as the numerical rating scale or visual analog scale. Pain management may involve medications, physical therapy, psychological interventions, and other treatments tailored to the individual's needs.
The Pain Scale in the US is a simple self-measurement "from 0 to 10" on which a patient ranks the pain they feel "in this moment".
Pain is subjective because different people experience it at different levels eg. bee keepers become acustomed to bee stings. For this reason pain is a qualitative factor and cannot be numerated with units and used in calculations.
General guidelines developed by the World Health Organization (WHO) have been developed for pain management.

Psychogenic pain is distinguished from somatogenic pain by the influence of psychological factors on the intensity of the patient's pain or degree of disability
A pain threshold is the point at which a person starts to feel discomfort or pain from a stimulus. It is the level of intensity at which a person perceives a sensation as painful. Different individuals have different pain thresholds.
It is an ordinal scale.
