Conversion class extension (extension methods and Parital class)

Question

I am creating a conversion class for the frequency, and I wanted my team to be able to add additional conversions when they are needed.

Frequency myFrequency = new Frequency(100, MHz);
double value = myFrequency.InKhz();

The source code for the class will not be included in future projects, so I will either have to have a class, or a partial class, or additional transformations must be extensions. An example would be adding a conversion to GHz

myFrequency.InGHz()

What is the best way to do this?

Update: after reading Randolpho's answer, I move on to the extension method. Since time allows the extensions to roll into the base code, but I did not want other team members to wait for updated assemblies, and this allows them to move on to the next task faster.

Otherwise, extension methods are likely to be your best option, but they will need to recompile + the new library anytime you want to add new conversions.
