| 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?
