Many early standards were based on the human body such as the length of the hand of a person, the width of his thumb, the distance between outstretched fingertips, the length of the foot of a person, and a certain number of paces, etc. In the beginning, while groups were small, such standards were convenient and uniform enough to serve as the basis for measurements.
Why is measurement important?
The wide scope of activities in the field of measurement testifies to their significant role in science and technology in the life of modern society. One can judge the general level of development of a society according to the condition and opportunities of the measuring service and metrological assurance. However, the great masses of measurement data which are obtained through the measurements are socially significant and useful only if their traceability and accuracy, irrespective of the place, time, and conditions under which they are taken, are assured. Measurement traceability is one of the most important tasks of metrology.
How is measurement culture related to human history?
The history of human civilization is closely connected with the development of the measurement culture. This is the process of continuous improvement of methods and means for measurement, and of systems ensuring measurement traceability based on improvements in accuracy and measurement uniformity, motivated by the increasing recognition of the importance of reference measurements as a necessary basis for both economic and state power. In other words, the entire history of human kind reflects the way that people have passed from measurements based on the senses to the scientific fundamentals of measurements which are the most important components of modern metrology, a science of measurements, methods and means for ensuring their traceability, and ways for reaching the required accuracy.
How did measurement change?
As the level of scientific sophistication improved, the basis for the measurement system changed dramatically. The earliest standards were based on the human body, and then attempts were made to base them on ‘natural’ phenomena. At one time, the basis for length was supposed to be a fraction of the circumference of the earth but it was ‘maintained’ by the use of a platinum/iridium bar. Time was maintained by a pendulum clock but was defined as a fraction of the day and so on. Today, the metre is no longer defined by an artifact. Now, the metre is the distance which light travels in an exactly defined fraction of a second. Since the speed of light in a vacuum is now defined as a constant of nature with a specified numerical value (299, 792, 458 metres per second), the definition of the unit of length is no longer independent of the definition of the unit of time.
What is measurement in the broad sense?
As per the first definition,’ the measurement in the narrow sense is an experimental comparison of one measure and to another, known one of the same kind (quality), which is established as a unit’ . A typical example is the measurement of physical quantities and application of the proportional scales. As per the second definition, ‘measurement in the broad sense is a search for correlations between numbers and states or processes according to a certain rule’.
How many units are there in the SI system?
Basic or fundamental standards – In the SI system, there are seven basic measurement units from which all other units are derived. All of the units except one are defined in terms of their unitary value. The one exception is the unit of mass. It is defined as 1000 grams (g) or 1 kilogram (kg).
