So if I vised the UK and you asked me how many kilometers away from my home in the USA I had to drive to grocery shop when I went home, I couldn't use that formula to give you my answer?

Actually - your answer is perfect (almost). Ignore my (unintentional) whimsy :)

Oh, I do enjoy your whimsy.

But I also respect your intelligence enough to wonder if I overlooked something.
Divide the number of miles by (.62). For instance, 3.1 miles divided by .62 will 5 kilometers.

Using the fact that 1 mi = 1.6093439999999998 km, or using fewer digits, 1.609344 km, we can multiply the number of miles by this quantity to obtain the number of kilometers that we want.

For example, if we want to know how many kilometers are in 25 miles, we can do the following:

25 mi * 1.609344 (km / mi) = 40.2336 km, or in scientific terms (using significant figures)
= 40. Km

I hope this helps.

That only works in the US (where you have funny little miles) :)
