Why are measurement important to scientists?
Measurements are important not only to scientists. And not all kind of scientists need measuring tools. Measuring instruments are mostly used by engineers, technicians. Engineeers use mostly calculators, it is their main device. There are test laboratories, telescopes, microscopes, a wide range of sophisticated equipment used by scientists. In fact measuring intruments are used by all technicians, engineers, and a lot of scientists on their respective fiedls.
What is the need for measurement of physical quantity?
We come across many things in our daily life that we need to measure. To go to the market in a rickshaw or a taxi we must know its approximate distance from our house. Only then would we have an idea of the expected fare. Similarly, to buy a cloth for our clothes, we should know the approximate length of cloth required. In certain cases we need to know exact values. For example, when we have to buy a pair of shoes, we require the exact size, or when we go to the tailor also requires the exact measurements. Any quantity that we study in physics is known as a physical quantity. Measurement of a physical quantity means comparing it with a known standard quantity. Each accepted standard quantity is a standard of measurement. It is called a unit.The measurement of a particular quantity is the same at all places and at all times. For this purpose, scientists have introduced some standard units for making physical measurements. The standard unit of a physical quantity should have the following characteristics.Fistly it is of a convinient size and secondly Its value dies not change with respect to place or time. A measurement consists of two parts-the magnitude and the units. For example, the length of a cloth is 5 meters. It means that 5 is the magnitude and meter is the standard unit. The study of physics involves measurement of various types. This is why physics is called the science of measurement. To make measurement more scientific, convenient and uniform, in 1791 the French Academy of Science devised the metric system based on the decimal system. In October 1990, the 11th General Conference of Weight and Measures adopted an international system of units known as the SI system of units.
Why do scientists need to be accurate when they measure?
because they just do
What is the formula for fiding the distance between two points?
This question is very vague, as there are numerous formulas, but they all require at least three pieces of information. You need a reference for making that measurement, unless you simply take the measurement yourself, in which case, you need no formula...get a tape measure
What scientists did not study the properties of light?
you will need to be a little more specific cause there are too many to list.
Why do scientists us a common system of measurement?
to share their data
Why do scientist need a common system of measurement?
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.

Why do you need a system of measurement?
So that when scientists make a project around the world, the pieces are the same size
What two parts does every measurement need?
metric system and English system
What does the word joules have to do with chemistry?
Joules are a measurement of energy. This has to do with chemistry because scientists and chemists need to be able to measure energy in chemistry experiment, and this is an accurate measurement.
Why do you need to learn how to convert unit system of measurement to another system unit of measurement?
Some instructions may call for a different measuring system, and it's just good knowledge to have. You never know when you might need it.
Why do you suppose there is not just one system of measurement?
Because the need for measurement is universal and it developed in different ways in primitive cultures. It is only later, with interregional, and then international trade that there was a need for a single system.
Why do scientists need the SKA telescope?
to observe the solar system
Why do you need a classification system?
so scientists can tell the difference between animals
Why do you think scientists use the metric system even though the US does not?
The SI system is the international standard, if scientists want to be understood, and taken seriously, on the world stage they need to use the SI system.
