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.

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