Re: currency conversion help please

You can use some measure like below. Check more details in the attached pbix.zip

converted sales =
IF (
    ISFILTERED ( conversionrates[To] ),
    SUM ( financials[sales] ) * MAX ( conversionrates[rate] ),
    SUM ( financials[sales] )
        * MAXX (
            FILTER ( conversionrates, conversionrates[To] = "USD" ),
            conversionrates[rate]
        )
)
//BY DEFAULT, it converts to USD
