| Hello,
|
| Is there any way to get numbers out of the 
constants defined in
| Miscellaneous`PhysicalConstants` package? 
Carrying units all the time
| is inconvenient in calculation.
|
| For example,
| In[1]:= << Miscellaneous`PhysicalConstants`
| In[2]:= VacuumPermeability
| Out[2]= \!\(\(p\ Second\ Volt\)\/\(2500000\ 
Ampere\ Meter\)\)
|
| I want to get the number p/2500000 out of 
VacuumPermeability, without
| units.  How can I do this?
