I do need this kind of pages, too... when I translate german recipes, where we have metric measures.... but I must admit, I usually use a german side ;o))
In our previous car I had fiddled with things on the dashboard and somehow got the a/c showing the temp in celsius. We never knew what the temp was in Farenheit for ages, but knew we were comfortable at 25C. Finally dh did something to return it to the reading we could understand. He won't let me change anything on the dash now.
