What is the importance of measuring tools

The goal of objective measurement is to produce a reference standard common currency for the exchange of quantitative value, so that all research and practice relevant to a particular variable can be conducted in uniform terms. The measurement should be taken perpendicular to the length of the fish.

Knowing the girth is important when trying to certify a fish for a record, and provides useful information to biologists about the relative condition of a fish. Kitchen measuring tools are essential to get the ideal blend of ingredients for any recipe. Part of the reason why some may fail in their cooking attempts is because they put in an inaccurate amount of ingredients. Measurement provides a standard for every day things and processes.

From weight, temperature, length even time is a measurement and it does play a very important role in our lives. Nor could you know how much fuel, oil, or transmission fluid your vehicle had, for without measurement there would be no fuel gauge or dip stick to check these fluid levels. Even if you could drive a car, you could never know how fast you were going because you would not have a speedometer. But, on the plus side, the police would never be able to pull you over for speeding because, without measurement, there would be no radar to enforce the speed limit.

Indeed, there could be no speed limits without measurement. At work , you could not use a computer, since computers require measurement in order to operate. Nor could you use a land-line telephone, cell phone, or fax machine to communicate with others, because these devices rely on measurement to operate. Forget about flying, or taking a bus, train, or ocean liner on an intercontinental business trip; and forget about traveling overseas.

Long-distance transportation and navigation would be impossible without the measurement of distance, speed, time, direction, and fuel. And with respect to business and commerce, forget about keeping track of financial revenues and expenses, profits and losses, or savings and costs.

Without measurement, people could not know how much money they have or how much money they are spending. On the positive side, however, without measurement you would never have to pay income taxes again, because the IRS could not operate without measurement. In a world in which no measurement tools exist, there could be no modern medicine, healthcare, surgery, pharmacology, radiology, dentistry, optometry, or audiology. And in a measureless world, there could be no science.

Numerous observers have emphasized the necessity of measurement in advancing human knowledge and understanding. Consider the following quotations:. I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science, whatever the matter may be… the grandest discoveries of science have been but the rewards of accurate measurement and patient long-continued labour in the minute sifting of numerical results.

Fortunately, we live in a world that allows us to make measurements. Measurement tools make our lives better and safer, and they enhance the quality and quantity of life. Arguably, the ability to measure physical properties accurately has tremendous survival value that gives humans an adaptive, evolutionary advantage honed through many years of natural selection. Thus, evolution may well have selected for measurement capabilities in human beings.

Draw students' attention to the exact measurements on each instrument and the units of measurement displayed. Use the measuring instruments several times to take measurements. Ask students if they can pinpoint any obvious flaws in the use of measuring instruments. Explain that problems can arise if there is no agreement on what each unit of measurement represents. Conclude your talk with a description of universal measurements. Related Papers. Engineering Drawing for Beginners.
