Mass measurements


Introduction

Note the distinction between the concepts of mass and weight:

  • Pasta It is the amount of matter that a body has, and is therefore constant anywhere on or outside the earth.
  • Weight of a body is the force with which this body is drawn (gravity) to the center of the earth. It varies according to where the body is.

For example, the mass of man on earth or moon has the same value. The weight, however, is six times greater on earth than on the moon. This phenomenon is explained by the fact that terrestrial gravity is 6 times higher than lunar gravity.

Note: The word grass, employed in the sense of the "unit of mass measurement of a body", is a masculine noun. So 200g, it reads "two hundred grams".

Kilogram

The fundamental unit of mass is called kilogram.

The kilogram (kg) is the mass of 1dm3 of distilled water at 4ºC.

Although the kilogram is the fundamental unit of mass, in practice we use the grass as the main unit of mass.

Note that each volume unit is ten times larger than the next lower unit. Examples:

1 dag = 10 g

1g = 10dg
