# PhysicalQuantityData

Calculate data related to physical quantities

Contributed by: Peter Cullen Burbery
 ResourceFunction["PhysicalQuantityData"][] lists every physical quantity. ResourceFunction["PhysicalQuantityData"][physicalquantity, property] calculates the value of the property for physicalquantity.

## Details

ResourceFunction["PhysicalQuantityData"] is a convenient short cut for "PhysicalQuantity” Entity values.
Supported properties include: "Abbreviations", "AlgebraicTypes", "AlternateNames", "BasePhysicalQuantity", "CanonicalUnit", "Classes", "Dimensions", "EntityClasses", "Instances", "Name", "NamedSIUnit", "PhysicalPropertyType", "QuantityVariable", "SIBaseUnit", "SIUnit", "StandardIdentifiers", "StandardSymbols" and "Symbols".
“PhysicalPropertyType" determines whether a quantity is extensive. Extensive properties are dependent on the amount of a substance but intensive properties are the same no matter how much you have of something. For example, density is constant but the mass and volume of an object changes:

## Examples

### Basic Examples

Find the SI base unit for magnetic inductance:

 In[1]:=
 Out[1]=

Compute extensive and intensive properties of the SI base quantities:

 In[2]:=
 In[3]:=
 Out[3]=

Select intensive values:

 In[4]:=
 Out[4]=

Get the base units:

 In[5]:=
 Out[5]=

Find instances of time:

 In[6]:=
 Out[6]=

Display the instances as a column of strings:

 In[7]:=
 Out[7]=

Display instances of mass in a column:

 In[8]:=
 Out[8]=

Display instances of length:

 In[9]:=
 Out[9]=

Get a random sample of 100 physical quantities out of all physical quantities:

 In[10]:=
 Out[10]=

Search for all names with "induct":

 In[11]:=
 Out[11]=

Find the units of each quantity with the name induct:

 In[12]:=
 Out[12]=
