Convert between crores, lakhs, arab, kharab, and western millions/billions. Indian numbering system cross-reference, comma placement, and scale comparison tables.
The Indian numbering system — used across India, Pakistan, Bangladesh, Nepal, and Sri Lanka — follows a different grouping pattern than the Western system. After thousands, Indians group digits in pairs (lakhs, crores, arab, kharab) rather than the Western triples (millions, billions, trillions). This frequently causes confusion when reading international financial news, comparing salaries, or interpreting business results.
This converter bridges the gap between the two systems. Enter any amount in lakhs, crores, arab, kharab, or Western units, and instantly see the equivalent in all other scales. The tool also demonstrates the Indian comma placement system (e.g., 1,00,00,000 for one crore versus 10,000,000 in Western notation) so you can verify numbers are formatted correctly.
Whether you are an Indian professional working with international clients, a Western investor evaluating Indian markets, or a student studying the numbering differences, this calculator eliminates the mental arithmetic of converting between these two widely-used but fundamentally different number grouping systems.
Converting between lakhs/crores and millions/billions requires dividing or multiplying by non-intuitive factors (1 crore = 10 million, not 1 million). Mental math errors are common and can be costly in business contexts. This tool handles all directions instantly and shows proper Indian comma formatting for clearer reports, pricing, and investor communication.
1 Lakh = 100,000 (10⁵) 1 Crore = 100 Lakhs = 10,000,000 (10⁷) 1 Arab = 100 Crore = 1,000,000,000 (10⁹) = 1 Billion 1 Kharab = 100 Arab = 100,000,000,000 (10¹¹) Crores to Millions: millions = crores × 10 Lakhs to Millions: millions = lakhs / 10 Crores to Billions: billions = crores / 100
Result: 100 Lakhs / 10 Million
1 crore = 1,00,00,000 = 10,000,000 = 10 million = 100 lakhs. In the Indian system, a crore is 100 lakhs. In Western terms, 1 crore equals 10 million.
The Indian system groups digits differently from the Western system after thousands. While the West uses groups of three (thousands, millions, billions), India uses an initial group of three followed by groups of two: thousands (10³), lakhs (10⁵), crores (10⁷), arab (10⁹), kharab (10¹¹). This creates the distinctive comma pattern seen in Indian numerical notation.
In Indian business and media, financial figures are almost always expressed in lakhs and crores. A company's revenue of "₹500 Cr" means 500 crore rupees (₹5,00,00,00,000 or approximately $600 million at typical exchange rates). Annual salaries are usually quoted in lakhs — "₹12 LPA" means 12 lakhs per annum (₹1,200,000).
The most common error is confusing crores with millions. When an Indian news article says "the project costs ₹200 crore," the Western equivalent is ₹2 billion (2,000 million), not ₹200 million. Always multiply crores by 10 to get millions, or by 10 million to get the exact number.
There are 100 lakhs in one crore. 1 crore = 100 lakhs = 1,00,00,000 (10 million). To convert crores to lakhs, multiply by 100.
Multiply the number of crores by 10. For example, 5 crores = 50 million. This is because 1 crore (10⁷) = 10 × 1 million (10⁶).
100 crores = 1 billion. Since 1 crore = 10 million and 1 billion = 1,000 million, you need 1,000 / 10 = 100 crores to equal 1 billion.
In India, commas are placed after the first three digits from the right, then every two digits: 10,00,000 (ten lakh), 1,00,00,000 (one crore). The Western system places commas every three digits: 10,000,000.
After crore comes arab (100 crore = 1 arab = 10⁹), then kharab (100 arab = 1 kharab = 10¹¹), then neel (10¹³), padma (10¹⁵), and shankh (10¹⁷). In everyday modern usage, most finance discussions stop at crore, arab, or billion equivalents.
The Indian numbering system has ancient Vedic origins and is deeply embedded in South Asian languages and culture. Numbers like lakh and crore appear in Hindi, Urdu, Bengali, Tamil, and other languages, making the system culturally natural for over a billion people.
