I was browsing one of those "movie mistake" sites and came across this in a Finding Nemo thread: "Factual error: In the scene where the fish tank has been cleaned by the newly installed laser fish cleaner, the machine states that the water temperature is '82 degrees.' In Australia the celsius scale is used; therefore, it should be about '28 degrees.' It is actually illegal to import or sell any instrument using 'Imperial' scales. You couldn't buy a Fahrenheit thermometer if you tried." Is this true? Is it illegal to own Imperial measuring devices in Australia? I find this very hard to beleive.
