Standard (metrology)
Standards in metrology can be compared to a ruler or a measuring tape that we use to measure the length of objects. Imagine that there are many different rulers or measuring tapes available, each one giving different measurements for the same object. This is because they have not been calibrated or standardized to give accurate and consistent measurements.
Similarly, in metrology, standards are used as a reference point to ensure that measurements are accurate and consistent. These standards are carefully manufactured to exact specifications and provide a known quantity of a physical parameter such as length, mass, time, or temperature.
For example, the International Prototype of the Kilogram (IPK) is the standard for the unit of mass (kilogram). It is made of platinum-iridium and kept under precise environmental conditions to maintain its accurate mass. All other kilograms around the world are calibrated against the IPK to ensure they give the same measurement for mass.
Having standardized measurements is vital in science, industry, and trade as it ensures that products and processes are consistent and reliable. Without standards, it would be difficult to compare measurements between different groups, countries or industries, leading to confusion and errors. Standards help ensure that the things we rely on every day, such as medical equipment, cars, and household goods, function correctly and safely.
