If you divide a kilometre distance by 8 and multiply by 5 to get miles, then get confused and divide the miles figure by 8 and multiply by 5 again. The two miles figures add up to roughly the original KM figure, at least to within speedo error.

Is there any practical application for this?

Isn't this just simple maths?

5/8 is the approximate ration between the equivalent km & miles.

It's like saying it is a strange coincidence that 5/8 = 10/16 = 1/1.6 = ad infinitum.

The coincidence is that it applies to KM to mile conversions, which made me wonder if there might be some practical application in calculations.

Don't get me started on litres per 100km being the worst ever way of judging fuel economy.....

Luckily EV cars are going to save us from this French insanity and give us a thousand scottish scientists per hour cool

Hmm, with a bit of fine tuning you may have found 'Jekyll's Constant', the latest to add to 'pi', 'e', c' and Avagadro.

Don't like Avogadro's, prefer ordinary pears.
