Where are you from if I may ask? As far as I’m aware they are are pretty common, I know only of India which does them differently and maybe US / Canada? Although I think the point and the comma are switched in some countries, so a thousand Euros would be 1.000,00€
No the ‘da’ is universal for ‘×10’. In german for example it’s also Mikro and languages can translate their prefixes as they want, as long as 1 km means 1000 meters and 1 ng means 1×10^-9 grams it is right by the International System of Units.
