As a result, consumers are protected from being overcharged or sold short-weighted products, and businesses are protected from unfair competition.

This helps to maintain a level playing field for all involved, promoting fairness and encouraging economic growth. Furthermore, accurate weights and measures also help to ensure product safety, as incorrect measurements can lead to dangerous products being distributed which could cause injury or even death.
