Convert numbers between billions, millions, trillions, lakhs, and crores. Shows number in words, scientific notation, and Western vs Indian numbering.
Large numbers are expressed differently across the world. The Western system uses thousands, millions, billions, and trillions, while the Indian numbering system uses lakhs (100,000), crores (10,000,000), and arabs (1,000,000,000). This difference creates constant confusion in international business, finance, journalism, and data analysis.
A "billion" in the Western short-scale system is 10⁹ (1,000,000,000), which equals 100 crores in the Indian system. Meanwhile, the British long-scale "billion" (10¹², now largely obsolete) adds another layer of historical confusion. Getting these conversions right matters when reading financial statements, GDP figures, population data, or budgets from different regions.
This converter translates any number between all major scales (thousands, millions, billions, trillions, lakhs, crores), displays the result in words, and provides scientific notation. The Western-to-Indian comparison table makes cross-system reading intuitive. Batch mode handles lists of figures from financial reports or datasets. Check the example with realistic values before reporting. Use the steps shown to verify rounding and units. Cross-check this output using a known reference case.
International business constantly requires converting between Western and Indian number scales. A startup valued at 5,000 crores needs to be reported as $600 million (or whatever the exchange rate yields) for US investors. GDP figures, government budgets, and corporate revenues all require accurate scale conversion.
This tool eliminates mental arithmetic with simultaneous output in all major scales, plus the number spelled out in words for verification. The batch mode is ideal for processing financial tables.
1 Billion = 1,000 Million = 100 Crores = 10,000 Lakhs 1 Crore = 10 Million = 100 Lakhs = 0.01 Billion 1 Lakh = 100,000 = 0.1 Million 1 Trillion = 1,000 Billion = 100,000 Crores
Result: 7.5 Billion
750 crores × 10,000,000 = 7,500,000,000 = 7.5 billion. This is a common scale for Indian company valuations expressed for international investors.
The Western system groups digits in threes (thousands): 1,000,000,000. The Indian system groups the first three, then in twos: 1,00,00,00,000 (100 crores). This difference extends beyond formatting — the named magnitudes are completely different, creating genuine confusion in cross-border communication.
| Power of 10 | Western name | Indian name | |---|---|---| | 10³ | Thousand | Hazaar | | 10⁵ | Hundred thousand | Lakh | | 10⁶ | Million | Ten lakhs | | 10⁷ | Ten million | Crore | | 10⁹ | Billion | Arab / 100 crore | | 10¹² | Trillion | Lakh crore |
Before 1975, a "billion" in British English meant 10¹² (a million million), not 10⁹. The UK officially adopted the short scale (1 billion = 10⁹) in 1975, aligning with American usage. France and some other countries still occasionally use the long scale, where "milliard" means 10⁹ and "billion" means 10¹².
**Finance:** Converting between crores and millions is daily work for investment bankers, analysts, and journalists covering Indian markets. An IPO valued at ₹10,000 crore is approximately $1.2 billion at current exchange rates.
**Government budgets:** India's Union Budget is presented in ₹ lakhs crore. Converting to billions or trillions for international comparison requires understanding both scales and the exchange rate.
1 billion = 100 crores. Conversely, 1 crore = 0.01 billion.
1 million = 10 lakhs. 1 lakh = 0.1 million = 100,000.
India uses lakhs (10⁵) and crores (10⁷) instead of the Western millions and billions. Numbers are grouped as X,XX,XX,XXX rather than X,XXX,XXX,XXX.
In the short scale (used by the US, UK, and most of the world today), yes. The obsolete long scale (formerly used in some European countries) defined a billion as 10¹². This converter uses the short scale.
In India, 1,00,00,000 is "one crore" (10 million) and 1,00,000 is "one lakh" (100,000). The comma placement differs from Western convention.
Quadrillion (10¹⁵), quintillion (10¹⁸), sextillion (10²¹), and so on. In the Indian system, the scale continues with kharab, neel, padma, etc.
