How to convert crores to pairs
To convert crores to pairs, multiply the number of crores by 5,000,000. This factor is exact. To go the other way, multiply pairs by 2×10⁻⁷.
pairs = crores × 5,000,000
Example: 10 crores = 50,000,000 pairs.
Large-number names differ around the world: this site uses the short scale (billion = 10⁹) by default, and lists the long-scale billion separately.
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).

Pair (pr)
Two items.
Pair comes from Old French paire, which grew out of Latin paria, the neuter plural of par, meaning equal. German Paar and Dutch paar are relatives of the same word. The core idea is two matching things taken together, as in a pair of shoes or gloves.
English also uses pair for single objects built from two connected parts. Scissors, spectacles, trousers, and jeans are plural-only nouns, so a counting word is needed: you say a pair of scissors or several pairs of jeans. That makes the unit slightly slippery. Six pairs of socks is 12 socks, but six pairs of scissors is only six objects. The word has other senses too, such as two people in a relationship or two cards of equal rank in poker, but as a quantity of loose items it is always two.
1 pair = 2 pieces (exactly).
