— How it works
Billion = crore ÷ 100. Crore = billion × 100. (1 crore = 10⁷, 1 billion = 10⁹.)
A hundred crore make a billion
A crore is 10,000,000 and a billion is 1,000,000,000, so it takes a hundred crore to reach a billion — they sit two powers of ten apart (10⁷ and 10⁹). This is the anchor at the larger end of everyday figures: 100 crore = 1 billion. It is the conversion you need for big company valuations, government budgets and tech funding, which Indian media often report in crore and international media in billion.
Common values: 1 crore = 0.01 billion 10 crore = 0.1 billion 100 crore = 1 billion 500 crore = 5 billion 1,000 crore = 10 billion 10,000 crore = 100 billion Going back: 1 billion = 100 crore, 5 billion = 500 crore, 50 billion = 5,000 crore.
Billion, arab and the written forms
In the Indian system, one billion also has a native name — one arab (100 crore). Written out, a billion is 1,00,00,00,000 in Indian grouping and 1,000,000,000 in international grouping. As always the digits match; only the commas move — the Indian convention grouping every two after the first three. The converter shows both forms so you can map a “500 crore” headline to “5 billion” at a glance.
