Properly jaw-dropping moment this evening: an e-mail from my US publisher saying that "since it's a science book", they'll publish Blue Machine WITH METRIC UNITS. So I don't have to convert everything to foot pounds per square elephant. In YEARS of writing for the US, this is the first time I have ever had a hint that there is a world outside feet and inches. Progress! #Books#Metric#Science
Science uses metric, worldwide. At my work we use microns and angstroms, for most things. Of course, we also use mils, but it's easy if you just remember there's 25.4 microns per mil.
