Part one of this series argued that traditional units are good for daily life: human-scaled, body-derived, requiring no equipment. The metric system, I said, is for science. I was being generous. The metric system isn't a rational system derived from nature. It's a fossil record of what a late-18th-century laboratory could measure. Every "fundamental" SI unit encodes the instrumentation limits of the Enlightenment, wrapped in a story about universality and reason.
