Each budget has one currency, chosen when you create it. You can change it in Job information until amounts are entered; after that it is fixed, so every figure in the budget means the same thing.
Most of the world's currencies are available. Currencies with three decimal places (such as KWD or BHD) are not.
Show a second currency
In the budget's Settings → Currency conversion, choose a Foreign currency and an Exchange rate (foreign per 1 budget currency). Converted totals appear on the summary and the PDF. Leave it as None to show one currency.
Rate cards keep the currency they were saved from. Filling a budget in another currency puts the rates in as they are, without converting them.
