India and South Asia use a distinct numbering system that groups digits differently from the Western system. Terms like lakh, crore, and arab are used in daily commerce, finance, real estate, and government reporting across India, Pakistan, Bangladesh, Nepal, and Sri Lanka. Understanding how to convert between crore and lakh — and between Indian and Western number systems — is essential for anyone working with South Asian financial data, reading Indian news, or managing businesses in the region.
Key Takeaways
- 1 crore = 100 lakh = 10 million = 10,000,000
- 1 lakh = 100,000 = 0.1 million — no direct 'million' equivalent in Indian system
- To convert crore to lakh: multiply by 100; lakh to crore: divide by 100
- 100 crore = 1 billion | 1 lakh crore = 1 trillion
- Indian comma placement: every 2 digits after the first 3 (e.g., 1,00,00,000 = 1 crore)
The Indian Numbering System: Lakh, Crore, and Beyond
The Indian numbering system uses different place values than the Western system:
Indian system place values: • 1 = One • 10 = Ten • 100 = Hundred • 1,000 = Thousand • 10,000 = Ten thousand • 1,00,000 = One lakh (100,000) • 10,00,000 = Ten lakh (1,000,000) • 1,00,00,000 = One crore (10,000,000) • 10,00,00,000 = Ten crore (100,000,000) • 1,00,00,00,000 = One arab (1,000,000,000)
Note the comma placement: In Indian notation, the first comma is placed after 3 digits from the right, then every 2 digits (e.g., 1,00,00,000 = one crore). Western notation places commas every 3 digits (10,000,000).
Key Indian terms: • Lakh = 100,000 (one hundred thousand) • Crore = 10,000,000 (ten million) • Arab = 1,000,000,000 (one billion) • Kharab = 100,000,000,000 (one hundred billion)
- 1 lakh = 100,000 (one hundred thousand)
- 1 crore = 10,000,000 (ten million) = 100 lakh
- 1 arab = 1,000,000,000 (one billion) = 100 crore
- Indian commas: placed after 3 digits from right, then every 2 digits
Crore to Lakh Conversion
The fundamental relationship: • 1 crore = 100 lakh • Therefore: Lakh = Crore × 100
Conversion table: • 0.1 crore = 10 lakh • 0.5 crore = 50 lakh • 1 crore = 100 lakh • 2 crore = 200 lakh • 5 crore = 500 lakh • 10 crore = 1,000 lakh • 25 crore = 2,500 lakh • 100 crore = 10,000 lakh
Lakh to crore (reverse): • Crore = Lakh ÷ 100 • 500 lakh = 500 ÷ 100 = 5 crore • 1,000 lakh = 10 crore • 50 lakh = 0.5 crore
In financial contexts: • A salary of ₹50 lakh = ₹0.5 crore • A property worth ₹2.5 crore = ₹250 lakh • A company turnover of ₹500 crore = ₹50,000 lakh
Mixed representations: "₹1.25 crore" = 1 crore + 25 lakh = 125 lakh = 12,500,000
- 1 crore = 100 lakh (multiply crore by 100 to get lakh)
- 1 lakh = 0.01 crore (divide lakh by 100 to get crore)
- 2.5 crore = 250 lakh | 0.5 crore = 50 lakh
- Mixed: ₹1.25 crore = 125 lakh = 1,25,00,000
Indian vs. Western Number System Comparison
Converting between Indian and Western notation:
Indian → Western: • 1 lakh = 100,000 (100 thousand) • 10 lakh = 1,000,000 (1 million) • 1 crore = 10,000,000 (10 million) • 10 crore = 100,000,000 (100 million) • 100 crore = 1,000,000,000 (1 billion) • 1 arab = 1,000,000,000 (1 billion) • 1 kharab = 100,000,000,000 (100 billion)
Comparison table: | Indian Term | Indian Value | Western Equivalent | |-------------|-------------|-------------------| | 1 lakh | 1,00,000 | 100 thousand | | 10 lakh | 10,00,000 | 1 million | | 1 crore | 1,00,00,000 | 10 million | | 10 crore | 10,00,00,000 | 100 million | | 100 crore | 1,00,00,00,000 | 1 billion |
Note: There is no direct Indian equivalent for 'million'. 1 million = 10 lakh. 1 billion = 100 crore (or 1 arab).
- 1 million = 10 lakh | 1 billion = 100 crore
- 1 lakh = 0.1 million | 1 crore = 10 million
- No direct 'million' term in Indian system — say '10 lakh' instead
- GDP reports: India's GDP reported in both systems in different media
Practical Applications in Indian Finance
Indian financial reporting uses crore and lakh extensively:
Real estate: • Property prices in Indian cities are quoted in lakh or crore • Affordable housing: ₹20–50 lakh • Mid-segment: ₹50 lakh–₹1.5 crore • Premium: ₹1.5–₹5 crore • Luxury: ₹5 crore+
Salaries: • Entry-level: ₹3–6 lakh per annum (LPA) • Mid-level: ₹10–25 LPA • Senior management: ₹25–100 LPA • CXO level: ₹1 crore+ per annum • Startup funding rounds are in crore (seed) or hundreds of crore (Series A+)
Government budgets: • Central government: reported in crore and lakh crore • 1 lakh crore = 1 trillion = ₹10,00,000 crore • India's Union Budget 2024-25: approximately ₹47.65 lakh crore (~$574 billion)
Stock market: • Market capitalization: Nifty 50 companies measured in crore and lakh crore • SEBI reporting: quarterly results in crore • Sensex/Nifty volumes: measured in crore of shares or lakh crore of trade value
- Property: ₹50 lakh = ₹0.5 crore (affordable); ₹2–5 crore (premium)
- Salaries: LPA (lakh per annum) — ₹10 LPA = ₹10,00,000/year
- 1 lakh crore = 1 trillion (used for national-level figures)
- Startup valuations: seed in crore, unicorns (>$1B) in thousands of crore

Frequently Asked Questions
How many lakh is 1 crore?
1 crore = 100 lakh. This is the fundamental conversion in the Indian numbering system. One crore equals ten million in the Western system, and 100 lakh in the Indian system. To convert any crore amount to lakh, simply multiply by 100. For example, 2.5 crore = 250 lakh.
What is 1 crore in millions?
1 crore = 10 million. Since 1 lakh = 0.1 million and 1 crore = 100 lakh, then 1 crore = 100 × 0.1 million = 10 million. So if an Indian news article mentions ₹50 crore, that equals ₹500 million or $6 million at an approximate exchange rate of ₹83/dollar.
What is 1 billion in crore?
1 billion = 100 crore. 1 billion = 1,000,000,000 and 1 crore = 10,000,000. So 1,000,000,000 ÷ 10,000,000 = 100. Therefore, if a company is valued at $1 billion, it's valued at approximately ₹8,300 crore (at ₹83/dollar).
Why does India use lakh and crore instead of million and billion?
India's numbering system evolved independently with groupings of two digits above the thousands place (ten-thousand, lakh, ten-lakh, crore) rather than the Western three-digit groupings (thousand, million, billion). The system is deeply embedded in Indian languages, culture, law, and commerce. The RBI, SEBI, and Indian courts use this system in official documents. Despite globalization, the Indian system remains dominant in South Asian business contexts.
How do I write 1 crore in numbers?
In Indian notation: 1,00,00,000. In Western notation: 10,000,000. The difference is in how commas group the digits — India uses a 3-2-2-2 pattern (starting from the right: 000, then groups of 2), while the West uses groups of 3. Both represent exactly ten million.
