Convert numbers between billions, millions, trillions, lakhs, and crores. Shows number in words, scientific notation, and Western vs Indian numbering.
Large numbers are named differently across the Western and Indian numbering systems. The Western system uses thousands, millions, billions, and trillions, while the Indian system uses lakhs, crores, and larger grouped units such as arabs.
This converter maps a number across those naming systems and shows the result in words and scientific notation. That makes it easier to compare financial, population, or budget figures when sources use different conventions.
The comparison table and batch mode are there to make cross-system reading less error-prone when the same magnitude is described in more than one way.
When a report uses crores but the audience expects billions, the size of the number is easy to misread. This page keeps the scale conversions and the number-in-words view together so the same value is easier to verify in both systems.
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.
Last updated:
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.
