I need to take liquid. It said 20 mg a day in USA but I live in Australia and have ml. So 20 mg is how much in ml? Thanks

The density of the liquid must be known in order to convert. If I knew the name of the liquid, I could find it's density and convert it for you.

I think you can figure this out ...
