What is an Inch?
An inch is exactly 2.54 centimeters — a rare case where an imperial and a metric unit line up on a tidy number, because the inch was redefined in terms of the meter rather than the other way round. It has quietly outlived most imperial units by attaching itself to technology: screen sizes, wheel and tyre diameters, plumbing pipe, and screw threads are specified in inches worldwide, so even in thoroughly metric countries people buy a 15-inch laptop and 17-inch wheels.
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.
To put both in perspective: an inch is about the width of an adult thumb, while a mile takes most people fifteen to twenty minutes to walk.
