How are the price point of certain currencies calculated?

[Grant]

With forex, it's all about the worlds money. We know they calculate how much certain currencies are worth depending on the country its used in. With that being said, how does forex decide on the worth of a nations currency? Like, how does forex decide on how much the USD is worth? I'm curious as I'm still fresh when it comes to forex and forex trading.

Certain currencies' price points are influenced by the industry's supply and demand for the currency. Political and economic trends, central bank
regulations, and rate of interest movements are all variables that impact currency supply and demand. The relative demand for two currencies
determines the rate of exchange amongst them.
