I suspect that this doesn't work properly for all cases of from_unit,
to_unit.
As a general case:
def temp ( T, u1, u2 ):
# from and to units the same, return T unchanged
# else use a conversion table
ct = { (a, b):lambda x: formula, .... }
return ct[ (u1, u2 ) ]( T )
Note you may need to build in case independence!

You completely missed the point of my earlier posts, and I suspect the
reason both these questions were included.
Firstly, consider that if temp (from q1a) works properly you can use temp
to convert the units of T2 to the units of T1, by calling:
temp( T2, u2, u1 )
q1b can be implemented in one line if temp from q1a works properly!

First calculate the annual interest as 1 + fraction where fraction is
interest % / 100
The calculate the compounded interest as annual ^ years
Finally multiply the compounded interest by the principal
Mathematically:
principal * ( ( 1 + ( period_interest_% / 100 ) ) ^ periods )
Again, this should be possible as a single line function. All you have to
do is turn the math into python code.
