In order to fully understand the meaning of the term balance, we must begin by discovering its etymological origin. In this case, we can state that it is a word that derives from Latin. Specifically, it comes from the noun “bilanx”, which is the name used to refer to a balance that had two plates. And it is that it was the result of the sum of these two components:
-The prefix “bi-”, which is equivalent to “two”.
-The noun “lanx”, which can be translated as “plate”.
The concept refers to device used to calculate the weight of things.
For instance: “My nutritionist recommended that I buy a scale so that I can evaluate the evolution of my weight”, “The greengrocer told me that his scale is out of calibration”, “The Russian boxer will step on the scales tonight”.
There are multiple types of scales that allow weighing items with very different characteristics. Scales, in particular, measure the dough of bodies: the amount of matter they have. The kilogram is the unit of dough of the International System of Units.
There are many types of scales that exist, highlighting those for animals, industrial, pocket, those used for trucks, jewelry, digital, pharmacy, dock, baby weights … The latter, for For example, as their name suggests, they can be found both in pediatric consultations, in pharmacies and even in homes, and their objective is to be able to know the weight of a young child. In this way, you can know if you are growing and gaining weight normally or not.
In the same way, it should not be forgotten that there are scales that have the objective of weighing very specific items. Thus, there are vehicles, parcels, animals, barrels, hoppers, laboratory, jewelry, food …
In addition to all the above, whatever the type, it is required that a balance be accurate, reliable, resistant, easy to use and that it can have really useful functions such as memory, for example.
Although there are differences between weight and the mass, in everyday language both notions are used as equivalents. Therefore, although the scale reveals the table of something, it is often said that it reports its weight.
The precision of the scales varies according to their use. In a butcher shop, to cite one case, it is sufficient that the scale works with an accuracy of grams. Thus the butcher can sell two kilograms of ribs (chops) or two hundred grams of minced meat. Instead, in a laboratory, a scale with milligram precision will be needed to prepare the drugs in their exact proportions.
