Chemical engineering, material science, mechanics (A scale to show the energy needed for detaching two solid particles) [33] [34] Cost of transport: COT = energy efficiency, economics (ratio of energy input to kinetic motion) Damping ratio
(Mass) Density (or volume density) ρ: Mass per unit volume kg/m 3: L −3 M: intensive Mean lifetime: τ: Average time for a particle of a substance to decay s T: intensive Molar concentration: C: Amount of substance per unit volume mol⋅m −3: L −3 N: intensive Molar energy: J/mol: Amount of energy present in a system per unit amount of ...
The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. By metonymy, the term "volume" sometimes is used to refer to the corresponding region (e.g., bounding volume). [2] [3]
It follows, for example, that the ratio of two extensive properties is an intensive property. To illustrate, consider a system having a certain mass, , and volume, . The density, is equal to mass (extensive) divided by volume (extensive): =.
Examples of physical properties that aren't characteristic properties are mass and volume. Examples of characteristic properties include melting points, boiling points, density, viscosity, solubility, Crystal structure and crystal shape. Substances with characteristic properties can be separated.
The volume of the auditorium is between 3 and 3.5 million cubic feet (between 85,000 and 99,000 cubic metres). [55] Melbourne Cricket Ground A common measure of volume in Australia, and in the state of Victoria in particular, is the Melbourne Cricket Ground, the largest stadium in Australia and 13th largest in the world.

In science, quantitative structure is the subject of empirical investigation and cannot be assumed to exist a priori for any given property. The linear continuum represents the prototype of continuous quantitative structure as characterized by Hölder (1901) (translated in Michell & Ernst, 1996). A fundamental feature of any type of quantity is ...
[19] [20] Examples of quotients of dimension one include calculating slopes or some unit conversion factors. Another set of examples is mass fractions or mole fractions, often written using parts-per notation such as ppm (= 10 −6), ppb (= 10 −9), and ppt (= 10 −12), or perhaps confusingly as ratios of two identical units (kg/kg or mol/mol).
