About these units
Great Gross (gt gr)
Twelve gross (1,728 items), the cube of twelve.
A great gross is twelve gross, which makes 1,728 items: a dozen dozen dozen, or 12 cubed. In duodecimal notation, where twelve is written 10, it is the number written 1,000. The number has a familiar cousin in measurement, since a cubic foot holds 1,728 cubic inches, because 12 inches times 12 times 12 is the same 12³.
Seen as a ladder, each step is a factor of 12: dozen 12, gross 144, great gross 1,728. A great gross equals 144 dozen, 288 half dozens, or 864 pairs. Terms this large are mainly used when buying or shipping goods in bulk, and the Dozenal Society of America, which advocates counting in twelves, promotes them as ready-made names for powers of twelve.
1 great gross = 1,728 pieces (exactly).

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).
