Unit of mass in the metric system, equivalent to one thousandth of a kilogram: one gram is equivalent to one cubic centimeter of distilled water at four degrees centigrade.
The mass of a body corresponds to the amount of matter it has and its unit of measurement is the gram. To symbolize the weight of the elements of greater or lesser mass, it is necessary to establish units of mass that are multiples or submultiples of the gram.
In addition to the gram (g), there are other units to measure increasing quantities, the most common are: kilogram (Kg), hectare (hd), decagram (dag), decigram (dg), scintigram (cg) and milligram (mg).
If you want to go from one unit to another, you must multiply (if it is from a larger unit to a smaller unit) or divide (if it is from a smaller unit to a larger unit) by the unit, followed by as many zeros as there are places between them. To transform the units of mass that are presented to us, we must multiply or divide by 10.
Another unit of measurement that is used to weigh items of great mass is the tons and 1 ton is equivalent to 1,000 Kg, that is, 1 ton is 1,000,000 grams.
The International System of Units is the system that is used throughout the planet, being the successor of the Decimal Decimal System. Among the great benefits offered by this system, which was established in 1960, is that the units that compose it are based on essential physical phenomena.
This system establishes seven basic units that in turn refer to physical quantities and the rest are derived from them. In the case that concerns us, the basic quantity is mass, symbolized by the letter M, the unit being the kilogram or kg.
