GramThe gram is a unit of mass which is part of International System of Units. Symbol g, the gram is equal to one thousandth of a kilogram. On the other hand, the gram is a unit of weight of the Metric system which is equivalent to the force exerted on a mass of one gram by the effect of gravity.

Taking into account that its definition is tied to the concept of kilogram (kg), it is important to mention that the kilogram is the basic unit of dough of the International System. The kg is defined by a standard (an international prototype), and not by a physical characteristic.

One gram, in short, is equivalent to 0.001 kilograms. Its submultiples are decigrams, the centigrams, the milligrams and the micrograms, among others. Its multiples, on the other hand, are units Like the decagrams, the hectograms, the megagrams and the gigagrams, in addition to the aforementioned kilogram.

The idea of ​​gram is used to refer to the amount of something whose weight equals precisely one gram. Yes one person He enters a warehouse and asks for 500 grams of chickpea flour, he is asking the seller to give him a quantity of this flour that has a weight of 500 grams.

It is common for many food products are marketed in grams and that their price is also expressed in this unit. The spices, for example, are usually sold in quantities of to grams.

When the amount of product that is sold or used is very large measured in grams, it appeals to the kilogram or other multiples of this unit.

GramIn popular language, since the gram represents lightness, we usually use this term to describe any object of little weight, or even to talk about people who are too thin. For example, it is possible to say “Marcelo weighs a gram” to refer to being too skinny. By convention, anything that weighs less than a couple of kilograms is considered light, since almost everyone can load it without much effort. This leads us to use expressions that include the word gram to intuit or estimate the weight of something that we consider easy to carry.

Regarding its etymology, we can say that the origin of the word gram found in greek gramma. It is interesting to note that at the beginning the meaning of this Greek word referred to a letter, and this is related to the concept of grammar; It was only when it came to Latin that it was given the meaning of “small stone used for weighing.” This expansion in the definition of gram was not done arbitrarily, but arose after comparing the proportion between a small unit of weight and a large one with a single letter and the entire alphabet.

The case of the word element has a similar history: since the ancient Roman alphabet began with the letters L, M, and N and the Latin term for the alphabet was elementum, they started to use the word element to describe any basic principle, rudiment or fundamental part of a word, as fundamental as the alphabet itself.

It is important to note that Spanish speakers tend to confuse the concepts of weight measure Y mass measure. As well explained in a previous paragraph, both the kilogram and the gram are two of the most common units of mass. Since weight is a force, for your measurement should be used newtons. Even the dictionary of the RAE mentions this confusion, but it is still present in popular language, largely due to the way in which food products are distributed, classified many times according to their weight but making use of their mass.
