I'm curious if anyone has any tricks for converting dollars to euros (or euros to dollars) quickly in your head. For example, to figure out how much to tip here at home, I double the amount of tax (8.6% x 2 - 19.2% tip).
I'm not an idiot (honestly, I have a graduate level education), but I just seem to have this mental block with numbers that I have to work to get past. Once I figure out a trick for something, I manage just fine.
I know the dollar keeps changing and that conversions are roughly $1.36. I don't care about complete precision of the exchange rates. I just need some easy trick to convert money in my head relatively quickly when making purchasing decisions.
