No doubt you are all aware of Fibonacci numbers, where the next number in a sequence is the sum of the previous 2, thus:

0,1,1,2,3,5,8,13,21,34,55,89 etc.

As there are just over 8km in 5 miles, and 8 and 5 are both Fibonacci numbers, you can use this to your advantage when travelling sur la continent and thus wanting to convert kilometres to good, solid, British miles. Simply note the number of kilometres to your destination, then take the previous number in the Fibonacci sequence. You now have a reasonably good estimate of the distance in readily comprehensible mileage.

The system of course works in reverse if you are of metric sensibilities. If you have trouble remembering which way round the numbers are, simply remember that the larger number always represents kilometres, which is a 'larger' word than miles.

Hoorah!

Or, you can just multiply the number of miles by 1.6 for a good approximation.

Erm - I am conscious that my total mathematical ignorance may be showing here, but you've given this list of numbers - what if the number of kilometres doesn't correspond to any of the numbers in the Fibonacci sequence you quoted?

Jenny, in that case, see my post above.

Well that's what I normally do Tas - or multiply by 5 and divide by 8 to get kilometres to miles, or multiply by 8 and divide by 5 to get miles to kilometres.

I think that's what most NORMAL people do, Jenny!

*glances at Southpaw*

Do you wanna tell him, or should I?

Well, personally my level of mental arithmetic is such that I find it easier to add 2 numbers together than multiply by anything with a decimal point in it, or divide by anything. As to Jenny's question, it is only a rough method for estimating the distance, so just pick a number near it!

It was only meant to be a bit of QI numberage, don't know why I bother, at least makes a change from 'your favourite shiny objects' mumble mumble

My favourite shiny object is my head.

If I can't be bothered to work out 1.6, I usually just times by 1.5 and add a bit.

Of course, usually I refuse to pander to these stupid Euro types and their eminently sensible kilometres. How dare they!

If your vehicle has a 'speedometer' marked in both MPH and KPH, a quick glance at the dial will give you instant conversion, either way.
This only works in proper cars; them Frenchy cars don't have proper speedos.

Unlike Frenchmen at the beach, who seem very keen to wear very small speedos.

Well, I at least found that QI, Southpaw :-)

Thank you, thank you gruff. It's good to know that not everyone in these here parts is a complete philistine.
