# What are weight measurements?

We explain what weight measurements are and what they are for. In addition, other less common weight measures.

1. ### What are weight measurements?

Weight units are called units conventionally used to calculate the weight of a body , that is, the amount of matter in it.

Although this magnitude is more commonly known as weight, we are actually talking about  mass ; since the first will be the extent to which, under the action of gravity , the object prints a force on the surface on which it rests, and is therefore measured in Newtons (N).

The mass , on the other hand, responds to the amount of matter of an object and uses conventional measures of gram (g) and kilogram (kg), among others.

The measure of weight to be used, in any case, will depend on many scientific and cultural variables, so that in some nations one system is used and in others another is used . To carry out measurements of this type, in any case, a balance is used: on one end or plate the object is placed and on the other side loads equivalent to its weight.

According to the International System, the standard measure of weight is the gram (g) , taken from the decimal metric system along with its extensive list of multiples: Decagram (Dg), hectogram (Hg) and kilogram (Kg) which represent 10, 100 and 1000 net grams respectively.

Below, however, there are also known submultiples: decigram (dg), centigram (cg) and milligram (mg). One gram was once defined as the mass of a cubic centimeter of water at a temperature of 3.98 ° C.

A measure of weight can become another thanks to a more or less stable and accepted conversion factor.
