About these units
Crore (crore)
Ten million (10⁷), or one hundred lakh. Written 1,00,00,000 in the Indian numbering system.
Sanskrit had separate words for most powers of ten from 100 up to 10 to the 19th. The crore comes from one of them: the Prakrit kroḍi, which derives from the Sanskrit koṭi, and in Hindi and Urdu it is karoṛ. In Tamil, Kannada and Malayalam the cognate is kōṭi. Outside South Asia, koṭi travelled mostly through Buddhist texts, and in Indonesian and Malay keti means 100,000, a lakh, instead of ten million.
A crore is 100 lakh, or 10,000,000, and is written 1,00,00,000 in Indian grouping. It is the natural unit for large sums of money in India, Bangladesh and Pakistan, so 150,000,000 rupees is 15 crore rupees. For amounts in the trillions, the system's next named units, arab and kharab, are rarely used, so people say lakh crore for 10 to the 12th. Nepal and Sri Lanka both used the system in the past but have moved to international numbering in recent years.
1 crore = 10,000,000 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).
