A physical relation between only the given physical quantities must be expressible as a relation between the nondimensional quantities.
There are usually fewer nondimensional than physical quantities, which reduces the number of experiments or numerical computations necessary to establish the physical relation to a specified resolution, in comparison with the number if all but one dependent physical variable were independently varied.
Also, the absence of any given physical quantity in the output reveals that either the quantity is irrelevant or others are necessary to describe the relation.

While human engineers can interpret these numbers as physical quantities by inferring dimension and units from context, the representation of quantities as numbers leaves implicit other relevant information about physical quantities in engineering models, such as physical dimension and unit of measure.
A meter is an example of an unit-of-measure for quantities of the length physical-dimension.
The physical-quantities theory defines the basic vocabulary for describing physical quantities in a general form, making explicit the relationships between magnitudes of various orders, units of measure and physical dimensions.

 Natural Length Contraction Due to Gravity
Classical physics with quantum mechanics alone lead to predictions, which are compatible with all the experimental observations usually attributed to relativity.
We know that a physical length is normally expressed as a pure number "x" of units when it is implied that the observer uses a universal system involving changeless reference units in all frames.
When needed, the number of units (of the physical quantity) is represented here by #r in the case of length, #m in the case of mass, and #E in the case of the number of unit of energy.

 Patent 4881071: Transducer for measuring one or more physical quantities or electric variables
When using data acquisition systems, a problem which is normally encountered is the physical connection between the transducer and the apparatus used for the acquisition of the measurement provided by a sensor.
The present invention aims at reducing in a substantial manner the costs associated with obtaining the measurements of the physical quantities and electric variables as well as the operating costs of the transducers involved in such measurements.
By using the present invention, it is not required that the transducers be equal in number to the number of the physical quantities and/or electric variables and that the timers be equal in number to the number of transducers, thereby providing important savings both as to the component costs and as to the operation thereof.
