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).

Billion (long Scale) (billion)
One million million (10¹²). The traditional British meaning, still used in much of continental Europe (e.g. German Billion). UK government usage switched to the short scale in 1974.
The long-scale billion is the older meaning, a million million, 10¹². The word was formed from million with the prefix bi-, so it named the second power of a million. The Oxford English Dictionary dates it to the 16th century, and French writers had already used bymillion in 1475 and byllion in 1484. On the long scale each new name is a million times the last: million, billion, trillion at 10¹⁸, with the 10¹⁵ step called a billiard.
Britain used this sense as its most common one until the 1950s, when the short scale began spreading through technical writing and journalism, and the government formally adopted the short scale in 1974. France reverted to the long scale in 1948. Today the long scale is used in continental Europe, French Canada, and the Spanish-speaking Americas, so the same word can mean either 10¹² or 10⁹ depending on the language, and a long-scale billion is 1,000 short-scale billions.
1 billion (long scale) = 1,000,000,000,000 pieces (exactly).
