Metrology

Metrology is the science of measurement. In practice, metrology helps ensure everything we measure like length, weight, temperature, or time, is accurate and consistent. It's used in everyday life and industries to make sure tools and devices give correct readings. Whether it's a ruler, a thermometer, or a machine in a factory, metrology makes sure the measurements are reliable and can be trusted, which is important for safety, quality, and fairness.

Metrology is the science of measurement. It includes both theoretical and practical aspects of measurement, regardless of the measurement uncertainty or field of application.

The Three Practices of Metrology:

• Scientific Metrology: Deals with the development of new measurement methods and standards.
  
  

• Industrial/Commercial Metrology: Ensures instruments used in manufacturing are precise and consistent.
  
  

• Legal Metrology: Ensures measurements comply with laws and regulations, often in trade (e.g., weighing and counting scales in markets).
