2. List of dimensionless quantities - Wikipedia

   en.wikipedia.org/wiki/List_of_dimensionless...

   This is a list of well-known dimensionless quantities illustrating their variety of forms and applications. The tables also include pure numbers , dimensionless ratios, or dimensionless physical constants ; these topics are discussed in the article.

3. Dimensionless quantity - Wikipedia

   en.wikipedia.org/wiki/Dimensionless_quantity

   Dimensionless quantities can be obtained as ratios of quantities that are not dimensionless, but whose dimensions cancel out in the mathematical operation. [19] [20] Examples of quotients of dimension one include calculating slopes or some unit conversion factors.

5. Dimensionless physical constant - Wikipedia

   en.wikipedia.org/wiki/Dimensionless_physical...

   In aerodynamics for example, if one considers one particular airfoil, the Reynolds number value of the laminar–turbulent transition is one relevant dimensionless number of the problem. However, it is strictly related to the particular problem: for example, it is related to the airfoil being considered and also to the type of fluid in which it ...

6. Quantity - Wikipedia

   en.wikipedia.org/wiki/Quantity

   Dimensionless quantities, or quantities of dimension one, [2] are quantities implicitly defined in a manner that prevents their aggregation into units of measurement. [3] [4] Typically expressed as ratios that align with another system, these quantities do not necessitate explicitly defined units.

7. List of physical quantities - Wikipedia

   en.wikipedia.org/wiki/List_of_physical_quantities

   Derived quantities can be expressed in terms of the base quantities. Note that neither the names nor the symbols used for the physical quantities are international standards. Some quantities are known as several different names such as the magnetic B-field which is known as the magnetic flux density , the magnetic induction or simply as the ...

8. Nondimensionalization - Wikipedia

   en.wikipedia.org/wiki/Nondimensionalization

   Although nondimensionalization is well adapted for these problems, it is not restricted to them. An example of a non-differential-equation application is dimensional analysis; another example is normalization in statistics. Measuring devices are practical examples of nondimensionalization occurring in everyday life. Measuring devices are ...

9. List of mathematical constants - Wikipedia

   For example, the constant π may be defined as the ratio of the length of a circle's circumference to its diameter. The following list includes a decimal expansion and set containing each number, ordered by year of discovery. The column headings may be clicked to sort the table alphabetically, by decimal value, or by set.
