Limpy - I suspect you could be right. I googled all the various measurements and honestly, someone needs to decide which one we should all be using!! Some brands use one and other brands use another, and one unit of measurement is shown as something like "ug" - I think that's the one for micrograms!!! There's nothing like making our lives even more complicated. I have acquired an entire carrier bag full of the stuff, enough for a year, I reckon. Happy days!
