In the Indian numbering system, a crore is a unit of measurement used to represent 10 million or 1,00,00,000. It is the second-largest unit after the lakh, which represents one hundred thousand or 1,00,000. The word crore has its origin in the Sanskrit language and was first used in ancient Indian texts such as the Rigveda, the Mahabharata, and the Ramayana.

In terms of money, large amounts in Bangladesh, India, Nepal, and Pakistan are often written in terms of crore. For example, 150,000,000 rupees is written as "fifteen crore rupees" or "₹15 crore". In the financial world, a crore is frequently used to represent large sums of money, such as investments, loans, and other financial transactions.

To convert crore to other units of measurement, we can use the following conversions:

• 1 crore = 10 million
• 1 crore = 100 lakh
• 1 crore = 1,00,00,000

Therefore, 1 crore has 7 zeros.
