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).

Quire (qr)
25 sheets of machine-made paper (24 for handmade and some specialty papers). One twentieth of a ream.
Quire comes from the Latin quaternum, by fours, which passed through Old French into Old English. The name made sense in manuscript days, when a quire was usually four sheets folded once, giving eight leaves. Once paper let binders stitch five to seven sheets at a time, the link to four faded.
Today a quire is normally 25 sheets, a twentieth of a 500-sheet ream. Handmade and specialty papers sold in 480-sheet reams still use quires of 24, which was also an older measure in Britain and the United States. Other counts have existed, including 15, 18, and 20, depending on the paper type. The damaged outer quires of a packed ream, called cassie or cording quires, held 20 sheets each. Blank-book binders sometimes use the word for 80 pages.
1 quire = 25 pieces (exactly).
