About these units
Million (M)
One million (10⁶).
Million comes from Italian. Old Italian milione was built from mille, a thousand, plus an augmentative ending, so it began as something like a big thousand. The name proved useful as a stem: by 1475 the French mathematician Jehan Adam was already building larger names from it, bymillion and trimillion, for 10¹² and 10¹⁸. The short and long scales agree on the million itself, 1,000,000 or 10⁶, and diverge only for the larger names. The SI prefix mega- stands for 10⁶.
Millions are hard to feel. Counting out a million items one by one is famously laborious, yet a million seconds lasts only about 11.57 days. A billion seconds, by contrast, is roughly 31.7 years.
1 million = 1,000,000 pieces (exactly).

Half Dozen (½ doz)
Six items.
Half a dozen is six, and the phrase is best known from an idiom: six of one, half a dozen of the other. The saying works because the two quantities are identical, merely named differently, so it dismisses a choice between two options as pointless. The unit rests on the dozen, which came into English from Old French douzaine and Latin duodecim, and halving twelve leaves a number that still divides evenly by two and three.
In counting terms, half a dozen is 6 pieces or 3 pairs, and two of them make a dozen. A gross contains 24 half dozens, and a great gross contains 288. Because the larger bulk units are all built from twelves, half a dozen fits into every one of them with no remainder.
1 half dozen = 6 pieces (exactly).
