Mass will always be a fixed quantity. Mass is not the same thing as weight. If one takes something with the mass of 5 kilograms to the moon, the mass does not change, even though the weight is only 1/6 of what it is on the Earth. The standard measurement used for this fixed quantity is always kilograms. The kilogram is an internationally recognized measurement for mass.

• A:

Mass is a measure of the amount of matter that an object contains, while density is a measure of how much mass an object contains per a unit volume. Mass is measured in kilograms, while density is typically measured in kilograms per cubed meter. Both are widely used in scientific formulas that are crucial for engineers, scientists and other professionals.

• A:

Density can be the amount of matter in a given volume, also known as mass density. Density can also be the number of objects in a given volume, known as number density.

• A:

Mass and weight are related in that mass is an important factor in calculating weight, but they are not alike. Mass is the amount of material present in any object, while weight is the measurement of the force with which gravity acts upon the object.
