Show price in eur and usd on website

I am looking to display a price in both Eur and USD on my own website.
Is there some Java, PHP, script doing this?

It is important the price is always displayed up-to-date (read: using the current valuta rating).

I’d suggest you fix a price in just one currency and let users figure it out at the time payment occurs… let the payment system handle the currency exchange rate.

Found a good solution:

If you use paddle, they offer you a price option for scripting.
So you can have prices auto translate on the website.
