The importance of measurements

Every scientific study begins from a first step consisting of observation, this being initially covered by the analysis of the general characteristics of a thing (so-called extrinsic analysis) for which later it is up to a vision much more thorough and precise of some of its characteristics, this being the intrinsic analysis that requires the application of appropriate optical and light instruments, among other tools.

In order to provide greater precision to this operation is also used to what are the measuring instruments.

The most well-known and often used form is in length measurements, is in the use of a ruler or tape measure or any instrument that allows us to compare around what is a unit.

It could be said then that the importance of making a measurement on something lies in obtaining an unknown data in reference to its comparison with a known data, being the first the characteristic inherent to the object that will be measured with the Instrumental Measurement, while the second is the measuring unit we have used to perform the comparison.

So in which situations in everyday life do we use the measurement?

• In the athletic competitions are measured the kilometers that are going to run.
• When you buy fabric in a warehouse they tell you how many meters you want.
• Buying fruit in a store
• By giving an indication about an address to a person.
• In the work the architects and designers measure the distances between walls to be able to know how much painting they are going in the decoration.
