What is Legal Metrology?

The study and research of measurements and weights are known as Metrology. Metrology with the application of law while providing instructions for the control of measuring equipment is called Legal Metrology. Additionally, it provides a guarantee for consumer safety, the environment, customers, and businesses, and it is necessary for fair trade. Errors in weight have the potential to significantly increase financial harm and have negative economic effects on the final consumers.
