How do you select between the different units?

I have been trying to use these libraries and specify metric units and not imperial.

How do I ask the print function to return a different units type?

Question relating to:

I was about to reply that the library seems incomplete and doesn't support metric units but then I noticed you've crated a fork and added them.

Yeah it doesn't support metric. The thing I haven't done before is how to do you pass the enum variable to the function? the temperature code has the following print function const char* print(unitsType units = CELSIUS); where unitsType is an enum with the values CELSIUS and FARENHEIT and KELVIN but then when you call the function t.print(CELSIUS) doesn't work because CELSIUS is not a known variable, I tried putting it in "" and '' and that doesn't seem to work so how do you pass the variable to it?

Thanks

const char* print(unitsType units = CELSIUS) used to default to imperial and as a work around i changed the default to metric.

Not sure how it works on this compiler, but you usually just give the fully qualified name like this: Temperature.CELSIUS, since the unitsType is public.
