Lakh and crore — Indian numbering for outsiders

Quick frame: Indian numbering uses lakhs (100,000) and crores (10 million) instead of the international thousands / millions / billions system. This isn't a quirk — it's a 4000-year-old Sanskrit numbering system that persists in Indian finance, media, and everyday speech. Use the Lakh / Crore Converter for quick conversions.

The Indian system

Indian	Numerical	International
1 thousand	1,000	1 thousand
1 lakh	1,00,000	100 thousand (0.1 million)
10 lakh	10,00,000	1 million
1 crore	1,00,00,000	10 million
100 crore	100,00,00,000	1 billion
1 lakh crore	10,00,00,00,00,000	1 trillion (US)

Beyond crore, Indians sometimes go to arab (10 billion), kharab (100 billion), but these are rarely used outside Sanskrit literature. Most Indian financial media stops at "lakh crore" for trillion.

Why 2-2-3 commas?

International convention groups digits in 3s: 1,000,000 (one million). Indian convention groups in 2-2-3: 1,00,00,000 (one crore). Both are correct — pick what your audience prefers.

In English-medium Indian newspapers and Bombay Stock Exchange filings, the 2-2-3 format dominates. International publications about India (Bloomberg, FT) use the 3-3-3 format.

Reading Indian financial news

Common headline phrases:

• "Reliance Q2 profit ₹15,000 crore" → ₹150 billion (US)
• "Adani revenue 9 lakh crore" → ₹9 trillion (US)
• "Uber India's revenue ₹4,500 crore" → ₹45 billion (US)
• "Average Indian household savings ₹2 lakh" → ₹200,000 (US)

Conversion shortcut: divide crores by 10 to get billions. Divide lakhs by 10 to get hundred-thousands.

When did India start using this system?

The roots are in Sanskrit numerology — sahasra (thousand), lakṣa (lakh), koṭi (crore), arbuda (arab). The system was used by ancient mathematicians like Aryabhata and Brahmagupta. British colonial administration kept it for India-specific contexts; post-Independence, RBI and SEBI standardised it.

Other South Asian countries (Pakistan, Bangladesh, Nepal, Sri Lanka) use the same system.

Common confusion

• "25 crores" spoken by Indians often means ₹25 crore (250 million) — not a typo for 2.5 cr.
• "1 lakh dollar" in old Indian English means 100,000 USD. Modern usage prefers $100k.
• "CR" in stock charts often abbreviates crore. PE multiples sometimes quote CR, sometimes "billions". Read footnotes carefully.

FAQ

Q. Why doesn't India just use millions? A. Cultural / linguistic preference. Most Indian languages have native words for lakh and crore. Switching would require relearning generations of habit. India's dual usage (lakh-crore in domestic, million-billion in international) works fine.

Q. Is "billion" commonly used in India? A. Increasingly yes — especially in tech sector and English media. But for everyday speech (real estate prices, salaries), Indians say "1 crore" not "10 million".

Q. How do I quickly convert? A. Lakh to thousand: add 2 zeros. Crore to million: add 1 zero. So 5 lakh = 500,000. 5 crore = 50,000,000 = 50 million.

Q. Which is bigger — 1 lakh crore or 1 trillion? A. They're equal. 1 lakh crore = 1,00,000 × 1,00,00,000 = 10^13 = 1 US trillion.
