What is a Mile?
The mile descends from the Roman mille passus — a thousand paces, each pace being two steps. Its modern length of exactly 1,609.344 meters looks arbitrary because it is: the figure was fixed by the 1959 international yard and pound agreement, which defined the yard as exactly 0.9144 meters and let the mile fall out of it at 1,760 yards. It remains the road-distance unit of the United States and the United Kingdom, and the unit runners think in for road races.
What is a Millimeter?
A millimeter is one thousandth of a meter, and it is where metric measurement starts getting genuinely precise. It is the working unit of engineering drawings, machine shops, rainfall figures and camera lenses — a "50 mm lens" and "12 mm of rain overnight" are both millimeter measurements. Technical drawings in most of the world default to millimeters precisely because it lets a draughtsman specify a whole component without ever writing a decimal point.
To put both in perspective: a mile takes most people fifteen to twenty minutes to walk, while a credit card is about 0.76 millimeters thick.
