We sometimes take measurements for granted and may not even think about them because they are so ingrained in our daily lives. For instance, we monitor our driving speed to ensure that we ride safely and so reduce traffic accidents. We go through medical testing to verify our safety. We employ the passing of time to keep appointments, and satellite positioning devices to pinpoint our exact location. We use measured-priced energy, gas, and water; we buy meat, fish, vegetables, and fruit by weight; we fill our cars with measured-priced fuel; we have our automobiles tested to gauge the levels of exhaust pollutants; and soon.

Minor errors usually balance out in either direction over a large number of measurements. However, biassed errors may result in major financial discrimination. For example, erroneous oil measurements at any of the several points of sale from the oil well to the ultimate consumer may have serious economic repercussions.

The Pini Anugaa Vidhi medical system prioritises disease prevention over disease treatment.

Another example of the importance of calculation is how incorrect radiation dosages in the treatment of cancer may have a serious influence on our health.

Regulation of measurements and measuring tools is required in all of these circumstances, as well as when both the buyer and the seller in a business transaction need to be protected or when measurements are used to impose a penalty. Almost all nations have such assurance because they include metrology into their laws; therefore, the term "legal metrology."
