Mathematical genius hiding in plain sight! The Fibonacci sequence (where each number is the sum of the two preceding ones: 0,1,1,2,3,5,8,13,21,34,55...) happens to be a surprisingly decent miles-to-kilometers converter! The "approximate km" column follows the sequence perfectly while the exact values are impressively close. Nature's mathematical pattern saves you from metric system panic! Next time you're traveling abroad without internet, just channel your inner Kowalski and recite the sacred number sequence. Who needs Google when you've got medieval mathematics?
