<p><em>Quantifiable</em> is an aspect class that affords to an entity properties for being measurable,
observable, or countable.

Focus nodes of this shape (qudt:Quantifiable) can have the following properties:

| qudt:hasUnit | <p>This property relates a factor unit to its unit or system of units with a unit of measure that is either: </p> <dl> <dd>a) defined by the system,</dd> <dd>b) accepted for use by the system and is convertible to a unit of equivalent dimension that is defined by the system,</dd> <dd>c) a reference to the unit of measure of a quantity (variable or constant) of interest.</dd> </dl> <p>Systems of units may distinguish between base and derived units. Base units are the units which measure the base quantities for the corresponding system of quantities. The base units are used to define units for all other quantities as products of powers of the base units. Such units are called derived units for the system. </p> | 0 | 1 | qudt:Unit | |
| qudt:relativeStandardUncertainty | The relative standard uncertainty of a measurement is the (absolute) standard uncertainty divided by the magnitude of the exact value. | 0 | 1 | xsd:double | |
| qudt:standardUncertainty | The standard uncertainty of a quantity is the estimated standard deviation of the mean taken from a series of measurements. | 0 | 1 | xsd:decimal | |
| qudt:standardUncertaintySN | The standard uncertainty of a quantity is the estimated standard deviation of the mean taken from a series of measurements. | 0 | 1 | xsd:double | |
