- adequate instruments metrologically checked
- a writed procedure for the measurement
- skilled operators
- a certified laboratory
- certified standard material
- good working conditions
There are a couple of ways to interpret your question. If you're asking "why do we have specific units that everyone agrees to," then it's because I want to know that we will agree on how much stuff I will get when I pay you some money.
If you're asking "why do scientists maintain a specific machine which is the official definition of a quantity," it's because once there is agreement, we need to have a way to compare everyone's measuring devices to be sure they will agree with the definition.
Scientifically, a standard is the agreed-upon device which provides the comparison for all other devices which make a particular measurement. All meter sticks must measure the same meter (to within reasonable precision depending on the stick) as the standard meter. All clocks should measure the same second as the standard second. Without standardspeople wouldn't know how to make instruments which agree with others.
So people in different countries can use it
Standard units are used to define measurements precisely and to a known base. Less errors occur if everyone uses the same standard units.
Standards of measurement are essential to communication and business.
is meant by measurement in che mistry
Standard measurements make it easier for everyone to know what that measurement means. The metric system, which is the standard system used by scientists, is specifically designed to be easy to use. The English system is much more complicated, mathematically.
Standard units of measurement allow other people to know what you mean when you use those units. To make this recipe you need four ounces of butter. OK, we know how much that is. If we had no standard units, it would be very hard to accurately convey exactly how much butter the recipe requires. And then what would your cookies taste like?

...the scientific method.

The Standard Method of Measurement known is the SMM7 publish by the the Royal Institution of the Chartered Surveyors is the appropriate method of measurement for building works. The SMM7 rules are simplified enough to produce shorter bill of quantities and the contents updated to conform to modern practice.
The Standard Method of Measurement is used for the measurement of construction works. It gives guidelines as to what should be measured for various parts of the construction process. It allows for estimators to measure works in a standard format for easy preparation of a Bill of Quantities nad easy comparisson of tenders.
Always.
The method that everyone has agreed to use.
Standard method of measurement (smm7) & project of international management
my standard measurement is 6 feet high
metric
easy to understand any one
Actually, about 3 countries use non-standard measurements - the SI is the international standard.
Standard measurements are rather like the standard meanings of the words that you and I are using to communicate with each other. If a word has a standard meaning, then when I use that word you will know what I mean. If I use a standard measurement, then I can tell other people what I have measured and they will know what the measurement means.
Yes you could. Look at metric and imperial measurement units, consider Roman units and the unit used by the Chinese empire as alternative units of measurement.
