Hi,
Azure Cost Management shows only data in the currency for which your billing account is. You can see screenshots from billing account and subscription showing the currency. In general Azure prices are in USD and converted to the currency of the billing scope. Check FAQ here thus you see your local currency and USD. You could get the usage data and convert it to amount in the currency you want by using retail prices API. but keep in mind that the API will give you the current prices. The retail prices could be different depending on the month and exchange rates.
