Using parts of the body for measurement can be unreliable as people's body parts can vary in size. For example, using a hand's width might be different for individuals with smaller or larger hands. This can lead to inconsistencies in measurement and lack of standardization. Additionally, cultural differences in body sizes and proportions can further complicate using body parts as a standard for measurement.
The two parts required to express measurement of a physical quantity are a numerical value and a unit of measurement. The numerical value indicates the magnitude of the quantity being measured, while the unit of measurement provides the context or scale for that value.
