It refers to a quantity that can have any value you want. Or perhaps any value within certain limits.
It's basically "some stuff, we're not sure how much" gussied up in pretty language.
A quantity is a numerical value that represents the amount or measurement of something, while a unit is a standardized amount used to measure that quantity. Quantity is the actual numerical value, while unit is the specific measurement scale used to quantify the quantity.
Arbitrary units in urinalysis refer to a method of measurement that does not have a standardized unit of measure. This means that the values obtained are specific to the particular instrument or test being used, and may not be directly comparable to results from other tests or devices. It is important to consider the specific reference ranges provided by the laboratory when interpreting results given in arbitrary units.
6.02 x 1023 atoms is an arbitrary number. Avagodro could have simply said that a "mole" is 12 atoms, or 1x1023 atoms, and achieved a similar result. When we say that a mole of a substance in a given reaction yields one mole of this atom and one-half mole of another we are essentially saying that for x amount of a starting chemical, we produce x amount of the first element, and 1/2 x amount of the second element. The x amount that we use could be 1000 atoms, 10,000 atoms, or 1x10100 atoms. In any case, we will get x number of one, and 1/2 x of the other, regardless of what x is. A mole, or 6.02x1023 atoms (or molecules) is the arbitrary number that we typically use. By contrast, acceleration due to gravity is NOT arbitrary. The mass of the earth determines that for objects near the surface of the earth, there will be an acceleration of 11.9 m/s2 regardless of what we choose to call it. So gravity is Intrinsic (forced by something else) where a mole is just a convenient (arbitrary) way to talk about a certain number of atoms (or molecules).
The number of the measured quantity is 351 grams.
California has released the greatest quantity of trichloroethylene into the environment.
they show the magnitude
Zero is a number (a scalar quantity without unit) while zero vector (or null vector) is a vector quantity having zero magnitude and arbitrary direction.
These are our output. But it is Arbitrary.
The rules were completely arbitrary.
Nobody made him do it; his decision was arbitrary.
Arbitrary Execution was created in 1989.
her choice of clothing seemed arbitrary!
He made an arbitrary decision to be on the green team. Most banks are prohibited from making arbitrary decisions on granting consumer loans. There is an arbitrary dividing line between VHF and UHF frequencies.
Nobody made him do it. His decision was completely arbitrary.
A government by absolute and arbitrary power is a a dictatorship.
A 'no parking' sign is non-arbitrary because it conveys a specific rule or regulation prohibiting parking in a certain area. It is based on established rules and is not subject to individual interpretation.
Wherever the person defining it choses to place it. That is why it is called arbitrary.
