By default 1 reward point = 1 unit of Woocommerce default currency. (You can check this value in Woocommerce -> Settings -> Currency options -> Currency.)
Accordingly, if your main currency is USD ($), then 1 reward point will be equivalent to $ 1. And for example, if a user uses 10 points to pay, he will receive a $10 discount. But I think this is so easy and understandable.
If your store has multiple currencies installed. Then when the user switches to another currency, bonus points will be automatically converted to the equivalent of the main currency.
For example, let’s say you’ve used the awesome currency switcher from WooBeWoo and your store has multiple currencies installed. For example, the main currency is Dollar ($) and you have set Euro (1€ = 1.1$) and Ruble (1$ = 75₽) as additional ones.
Thus, when the user switches between currencies, everything will be automatically converted.
