Pub Curmudgeon on yesterday's post:
As fuel is actually sold in litres, it might make sense to use miles per litre, but mpg is the established figure, and creating a hybrid unit combining Imperial and metric units would annoy a lot of people on both sides of the debate.
I'm not sure it would. There are already examples of mixed units, my favorite being tyre sizes:
HOW TO READ YOUR TYRE SIZE
Example: 215/60R15
215 is the width of the tire in millimetres.
60 is the aspect ratio or tire profile.
R means it is radial construction.
15 is the diameter of the wheel rim in inches.
Yup, they mix metric, imperial and a ratio - 60 = 60% of 215mm = 129mm = the distance between the edge of the rim and the tread, or possibly shoulder, of the tire.
