What is Lakh, Million, Crore, Billion, and Trillion?
What is a Lakh?
A lakh (L) is a unit in the Indian numbering system equal to 1,00,000 (10⁵). India, Pakistan, Bangladesh, Nepal and Sri Lanka use it for salaries, savings and flat prices. 1 lakh = 0.1 million.

What is a Crore?
A crore (Cr) is a unit in the Indian numbering system equal to 1,00,00,000 (10⁷). Union Budget lines and Indian annual reports are stated in crore. 1 crore = 10 million = 100 lakh.
What is a Billion?
A billion (B) is a unit in the International number system equal to 1,000,000,000 (10⁹). The Indian numbering system names the same quantity 1 arab. 1 billion = 100 crore = 10,000 lakh.

Indian vs. International Numbering System
The two systems group digits differently above the thousands place. The Indian numbering system adds a comma every two digits and names each step lakh, crore and arab. The International number system adds a comma every three digits and names each step million, billion and trillion.
Both agree up to 1,000 and diverge from 1,00,000 upward, which is why 75,31,08,642 in Indian digits is written 753,108,642 internationally.
