Billion vs Arab — Which Is Bigger?
1 billion and 1 arab are exactly the same size. Both are 1,00,00,00,000 — 10⁹. They are two names for one quantity, one from each numbering system, so neither is larger and converting between them changes nothing but the word.

| 1 Billion, Indian digits | 1,00,00,00,000 |
| 1 Billion, international digits | 1,000,000,000 |
| 1 Billion as a power of ten | 10⁹ |
| 1 Billion on the other scale | 1 Arab |
| 1 Arab, Indian digits | 1,00,00,00,000 |
| 1 Arab, international digits | 1,000,000,000 |
| 1 Arab as a power of ten | 10⁹ |
| 1 Arab on the other scale | 1 Billion |
Both directions
There is no conversion to do. Billion and Arab both mean 10⁹, so any amount carries across unchanged: 5 billion is 5 arab, 250 billion is 250 arab.
What changes is the audience. Billion belongs to the international scale and Arab to the Indian one, so the choice of word signals which system you are speaking in, not which quantity you mean.
Where each one is used
Billion is the international unit for company valuations, national budgets and populations. Because 1 billion is exactly 1 arab and exactly 100 crore, it is also the cleanest bridge between the two systems.
Arab is the classical unit above crore. It stays in daily use in Pakistan and in Urdu-language media, while Indian English has largely dropped it in favour of counting on in crore. This is the single biggest divergence between Indian and Pakistani number habits.

Frequently asked questions
Which is bigger, billion or arab?
Neither. 1 billion and 1 arab are both 1,00,00,00,000. The two words come from different numbering systems but name the same quantity.
How many arabs are in 1 billion?
One. They are the same unit under two names.
Why do the two systems have different units at all?
The international system introduces a new name every three digits — thousand, million, billion, trillion. The Indian system introduces one every two digits after a thousand — lakh, crore, arab, kharab. Both count the same way; they just group and name the digits differently, which is also why Indian commas fall at 1,00,00,000 rather than 10,000,000.
Is 1,00,00,00,000 the same as 1,000,000,000?
Yes — those are the same number written with Indian and international commas. Only the punctuation changes; the digits and the value do not.
