How to display the price in another currency on the site?

Question

WordPress

How can I add a price display in another currency?

Answer 1

The most incorrect option.
Store somewhere the exchange rate that you need.
And every time you render a page, calculate the cost.
Correct option.
Store the exchange rate somewhere, make another field for the product where you will write down the price in the corresponding rate and you will simply display it and that's it.
And in general, write what is your difficulty? That does not work?
