I’m using English and Metric weights and measures throughout Lt. Leary Commanding, as I did in With the Lightnings. I wouldn’t bother mentioning this, but the decision seems to concern some people. I’m doing it for the same reason that I’m writing the novel in English instead of inventing a language for the characters of future millennia to speak.
I’d like to note for those who’re interested that the orders in Chapter Nine are a close paraphrase of those which sent the frigate USS Congress to Hawaii in 1845. Here as elsewhere, I prefer to borrow from reality rather than invent it.
