Since 1 US Dollar is equal to 345.51 Hungarian Forint, we could say that n United States Dollars are equal to 345.51 times n Hungarian Forint. In other words, we could use the following formula:
Hungarian Forint = United States Dollars x 345.51
For example, let's say that we want to convert 2.0 United States Dollars to Hungarian Forint. Then, we just replace United States Dollars in the abovementioned formula with 2.0:
Hungarian Forint = 2.0 x 345.51
That is, 2.0 United States Dollars are equal to 691.02 Hungarian Forint.
