About these units
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).

Billion (short Scale) (B)
One thousand million (10⁹). The meaning used in the US, UK and most English-speaking countries today.
For decades British and American speakers meant different things by billion. The short-scale sense, a thousand million, took hold in the United States in the 19th century, while Britain kept the older meaning of a million million. From the 1950s the short scale spread through British technical writing and journalism, and Winston Churchill had remarked in 1941 that for practical financial purposes a billion was a thousand millions.
The official break came on December 20, 1974. Asked in Parliament whether ministers would be required to use the traditional British meaning, Prime Minister Harold Wilson answered no, explaining that billion was now used internationally for 1,000 million and that using it any other way would cause confusion. He conceded it could still be read as a million million and asked colleagues to avoid ambiguity. Today a billion is 10⁹, matching the SI prefix giga, and the UN projected that world population would reach 8 billion on November 15, 2022.
1 billion (short scale) = 1,000,000,000 pieces (exactly).
