Speed, density and pressure are examples of compound measures which means they are made up of two or more other measures. For example, speed is made up of distance and time. To convert the units ...
If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The units for density will be g/cm³. Arrangement of atoms in different metals is similar.
Density in particular is an important property ... point and the boiling point (also at sea level pressure) taken as 100 units, measured in terms of the change in volume of a fluid.
