How do steam gift cards translate over?

[thats a little punni]

I know its a bad question, but heres whats up
My friend from the US wants to give me a gift card, however, I'm from Brazil
I know it translates over, however, what I feel curious about is
Does it translate over the exact price of the gift card (ex: 15 usd gift card > 15 reais) or does it convert the currency? (ex: 15 usd = 73 reais)

Read the green box. If your friend wants to send you Steam money, better do with a digital gift card.

... or PayPal or Western Union or some other means of money transfer. Like wiring the money over.

What happens if my friend lives in another country?
The digital gift card you purchased will automatically be converted into your friend's currency.

If its 30 USD - its 30 USD - currency exchange rates not withstanding.

If your uncertain - ask them what currency they read on their account - then take a trip to google and do some calculations.
