Need the name field of your plugin in db to display a product price

Hello,
Could you tell me what is the name of the field value for the converted price that display the current currency applied ?
I am building a form and I need to dynamically fill a field with the product price, but I want it to match the currency switcher result, if possible with the currency symbol.
If CHF is selected by the visitor I need my field to have the price in CHF for exemple.

Thank you.
