I know it's a dumb trick but it works for me: I use the Fibonacci sequence. 3 miles? 5 km. 8miles? 13km. 33 miles? 55km.
My dumber version: Just multiply by 1.5. It's fine unless you are using a treasure map.
Same here. Usually it's x1.6 but 1.5 is easier to calculate and you add a teeny bit after.
Mine is divide by 3, multiply by 5. Simple and quite accurate.
Ha! That’s nice.
I never realized 1.609 miles/km is close to the golden ratio (1.618)
It is quite clever. My own rule of thumb is "add half of the amount in miles, then 10% of the (original) amount in miles". What's interesting is that it happens to be just as precise as the method shown above (ie. 1.6 v 1.609 v 1.618 )
Hey, this is very smart. The golden ratio... Wow!
