Convert a quantity into Stoney natural units

Contributed by: Peter Burbery

ResourceFunction["StoneyUnitConversion"][quantity]

attempts to convert the specified quantity to Stoney units.

Details

Stoney units are based on the fundamental constants of the speed of light c, the coulomb constant 𝒦e, the gravitational constant G and the elementary charge ℯ.
Stoney UnitDefinitionValue in SI Base Units
Length1.3807*10-36m
Mass1.8592*10-9kg
Time4.6054*10-45s
Electric CurrentIS=ℯ1.602176634*10-19C
ResourceFunction["StoneyUnitConversion"] will output a unit in Stoney natural units (Stoney time, length, mass and electric current).
The input quantity must be a quantity such as Quantity[49,"Meters"] or Quantity["Meters"].

Examples

Basic Examples (1) 

Find how many Stoney units 8103 farads are equal to and the dimensions:

In[1]:=
ResourceFunction["StoneyUnitConversion"][Quantity[8103, "Farads"]]
Out[1]=
In[2]:=
QuantityUnit[ ResourceFunction["StoneyUnitConversion"][Quantity[8103, "Farads"]]]
Out[2]=

Scope (2) 

StoneyUnitConversion threads over lists:

In[3]:=
ResourceFunction[ "StoneyUnitConversion"][{Quantity[1, "BohrRadius"], Quantity[2, "Picograms"], Quantity[3, "Microseconds"]}]
Out[3]=

StoneyUnitConversion accepts QuantityArray arguments:

In[4]:=
ResourceFunction["StoneyUnitConversion"][ QuantityArray[{2.3, 1.5, 9.0}, "Angstroms"]]
Out[4]=

Applications (1) 

Express some fundamental constants in Stoney units:

In[5]:=
ResourceFunction[ "StoneyUnitConversion"][{Quantity["BoltzmannConstant"], Quantity["GravitationalConstant"], Quantity["ReducedPlanckConstant"], Quantity["SpeedOfLight"], Quantity["CoulombConstant"], Quantity["ElementaryCharge"]}]
Out[5]=
