Re: How Many Televisions Do You Have?
No they don't. Well, I don't.But our tv measurements are still in inches. Australia has been metric for decades now, but there are still too many poms over here desperately clinging on to the ancient way of measuring.
But looking on the bright side of life...Sometimes the sizes are given in both, inches and cm.

Yes, I think we ought to go back to cubits (based on the distance from the elbow to the fingertips). The measurement being taken from an arbitrary average person. We could then all go around the television shops with our cubit measuring devices, place them across the screen and get some idea of whether the TV would fit into the available space at home.

Of course, these are not comparable to those of other people, but if I need a quick means of measuring and don't have a ruler or tape measure handy, my hand will do!
I also find it easier to visualise longer distances in feet than in metres. I suppose it depends on how you were brought up. When ah wer a lad ther wer non o these metre things, and don't get me started on grams.
The Romans had the right idea.

The ratio of the sides are constant (though they have changed from 4:3 to 16:9) but Pythagoras's theorem means you can work out the sides from the just knowing the diagonal
Basically, for a modern wide screen TV it breaks down to
Height = 0.49 x Screen Size diagonal
Width = 0.87 x Screen Size diagonal
