Converting from one currency to another is done by a ratio calculation using the starting value and the Euro Exchange Rates below for the currencies being compared. Converting from Currency 1 to Currency 2 we state: Value in Currency 1 is to Value in Currency 2 as Rate in Currency 1 is to Rate in Currency 2.
\[ \dfrac{Value1}{Value2} = \dfrac{Rate1}{Rate2} \]solving for Value2
\[ Value2 = Value1 \times \dfrac{Rate2}{Rate1} \]Example, 100.00 HKD Hong Kong Dollar is how much USD United States Dollar?
Let's assume our daily rates are HKD = 9.53 EUR and USD = 1.23 EUR. Converting we use:
\[ Value2 = Value1 \times \dfrac{Rate2}{Rate1} \] \[ Value2 = 100.00 \times \dfrac{1.23}{9.53} = 12.907 USD \]Euro (base currency) exchange reference rates as of 10 May 2024.
