Product Price

Hello.
In the admin panel, I indicated the main currency $, that is, the prices for the goods I indicate in $
But on the window, I would like to see the converted amount in "rur" at the rate that I indicated for the "rur" in the currency section.
How to do this, please tell me.

What do you mean by "on the window" ?
