Summary of Fundamentos de la Metrología

00:00:00 - 00:05:00

The video discusses the science of metrology, which is the science of measuring and maintaining the accuracy of instruments. It explains the importance of using standard reference materials, such as a kilogram weight pattern, to ensure accurate measurements. The National Metrology Institute is responsible for maintaining National Standards in all dimensions of measurement.

• 00:00:00 In this video, the basics of metrology are discussed, including how measurements affect our daily lives. We've asked ourselves, for example, how many times a day we measure something, constantly when we go to the grocery store and weigh an item we buy, when we go to a gas station, or when we have a temperature and want to know our body's temperature. In addition, we put a thermometer under our arm. Then, not only is it questioned once or twice a day what the effect of a measurement would be with an incorrect result, but also the impact an incorrect measurement would have on our decisions with respect to certain situations is evident. If the results of measurements are incorrect, we are saying that the decisions we take based on those measurements are incorrect. And, as a result, our actions would be based on erroneous results, and the resolutions we take in response to those measurements are therefore incorrect. Science concerned with ensuring all measurements are correct is called metrology, and our understanding of it comes from our knowledge of measurements. All that relates to making accurate measurements is called knowledge, and includes the science of measuring objects with known property values, such as a kilogram weight pattern or temperature pattern. We need to have references against which to calibrate our

It discusses the importance of using standard reference materials, such as kilograms of a given substance, to ensure accurate measurements. The National Metrology Institute (NMI) is responsible for maintaining National Standards in all dimensions of measurement, such as physical and chemical.
