How Many Zeros in a Arab?
An arab has 9 zeros in the Indian numbering system: 1,00,00,00,000 — equal to one billion (1,000,000,000) in the international system, or 109. The arab is used in India, Pakistan, and Bangladesh as part of the extended Indian numbering scale: lakh (105), crore (107), arab (109), kharab (1011). One arab equals 100 crore or 10,000 lakh. In the Indian comma convention, an arab is written as 1,00,00,00,000 — groups of two digits separated by commas after the initial three rightmost digits. Learn more about crore zeros.

Are 1 Arab and 1 Billion the Same?
Yes — 1 arab and 1 billion represent exactly the same quantity. Both equal 109 = 1,000,000,000. The difference is purely linguistic and regional: "billion" is the standard international term from the short-scale system, while "arab" is the traditional Indian numbering term for the same value. In financial and scientific contexts, the two are interchangeable.
| Term | System | Value | Zeros |
|---|---|---|---|
| Arab | Indian | 1,00,00,00,000 | 9 |
| Billion | International | 1,000,000,000 | 9 |
Because they are the same number, 1 arab rupees is identical in value to 1 billion rupees — just stated in different numbering traditions. Learn more about how many zeros does a kharab have.
How Much Is 1 Arab in Crore?
One arab equals exactly 100 crore. Since 1 crore = 107 and 1 arab = 109, the ratio is 109 ÷ 107 = 100. This conversion is commonly used in Indian financial reporting where large national figures — government budgets, GDP components, and corporate revenues — are sometimes stated in arab but need to be cross-referenced with crore-based reporting.

How Many Zeros Are in 10 Arab?
Ten arab = 10,00,00,00,000, which has 10 zeros in total (the 1 is the leading digit, followed by 10 zeros). Multiples of arab scale up three zeros at a time when moving to the next named unit:
- 1 arab = 1,00,00,00,000 — 9 zeros
- 10 arab = 10,00,00,00,000 — 10 zeros
- 100 arab = 1 kharab = 1011 — 11 zeros
The arab sits at a convenient midpoint in the Indian extended scale — large enough to express national economic figures, yet still smaller than the kharab (1011) and neel (1013) that appear in formal Hindu astronomical and accounting traditions.
