Matter

Matter simply refers to any physical object composed of an amount of material.

The amount is counted in square units (u2), which is proportional to the space occupied by the material.

Properties
Many physical properties of an object can be directly calculated from the amount of matter and it's composing material's properties.

Size
Size and dimensions will depend on the shape of the object, but the total occupied space will always be equal to the amount (u2). For a pellet of matter, as an example, the radius (u) will be calculated from the formula $$r = \sqrt{A/\pi}$$

Mass
The mass (g) of the object will depend on the object's material density (g/u2) multiplied by it's amount (u2).

Examples

 * Plant pellets
 * Meat pellets
