unitConvert isn't converting to Hz

Question

I'm using symunit and need to convert 1/sqrt(Henry*Farad) to Hz. I have the following test code:

L = 10*u.nH;

C = 10*u.fF;

unitConvert(1/sqrt(L*C), u.GHz)

The output is:

1/(10*([fF]*[nH])^(1/2))

I think it should be in Hz but it doesn't convert to it. Am I wrong in saying Hz = 1/sqrt(Henry*Farad) or is it something wrong in the code?

Hi Henrique.

you can get there with

u = symunit
L = 10*u.uH;
C = 10*u.fF;
unitConvert(simplify(unitConvert(1/sqrt((L*C)), u.sec)),u.GHz)
ans = 10^(1/2)*[GHz]

but of course it would be a lot better if it just did the conversion you wanted in the first place.

Thank you it has worked!
