A comment on Using Fibonacci Numbers to Convert from Miles to Kilometers and Vice Versa. Parent comment
Take your kilometres e.g 60, divide by 5 -> 12, now times that by 3 -> 36.
Take your miles e.g 80, divide by 5 -> 16, times 8 -> 80 + 48 -> 128
So any conversion reasonable conversion can be done in your head with your 3, 5, and 8 times tables
