What's This 'Real Money' Stuff?
In your article you refer to American Fahrenheit, and the real money being Celcius.
In a land where we buy petrol by the litre but have road signs in mph I don't think we should be too robust in our condemnation of alternative measurement units.
And some of us prefer the real mccoy that the US sometimes offer. Everyone knows that when temperature is measured in Fahrenheit it is warmer.
And when I'm measuring for curtains give me feet and inches any day.
