Setting a base currency and exchange rates
Before you can make currency conversions, you need to choose a base currency (usually 
your domestic currency) and add exchange rates.
Note: The rate of the base currency is always 1. The base currency determines the 
conversion rates of the other currencies.
Example: If you set 
the Euro (EUR) as the base 
currency, a United 
Kingdom Pound (GBP) is 
approximately 1.63575 
EUR. Thus, you would 
write 1.63575 as the 
exchange rate for the GBP.
Select 
Currency
 as the measure type and select

currencies opens and you can see the current base currency at the top.
To change the base currency, scroll to the currency (usually your domestic currency), 
and select 
Options
→

Important: When you change the base currency, all previously set exchange 
rates are set to 0 and you need to key in new rates.
Add exchange rates, scroll to the currency, and key in a new rate, that is, how many 
units of the currency equal one unit of the base currency you have selected. See the 
example on the side of the page.
After you have inserted all the needed exchange rates, you can make currency
