Is 1 Arab equal to 1 billion

Yes, in the Indian and Arabic numbering systems, 1 Arab (also spelled Arb or Arawb) equals 1 billion in the international system, which is 100 crores. This term is primarily used in India, Pakistan, and some Middle Eastern countries as part of their traditional numbering hierarchy.

The Indian system extends beyond crores with terms like: 100 crores = 1 Arab, 100 Arab = 1 Kharab, 100 Kharab = 1 Neel, and so forth. While "crore" is widely understood and used in business, media, and finance throughout India, "Arab" and higher terms are less commonly used in mainstream discourse, appearing primarily in traditional contexts, certain regional usages, or very large government budget discussions. Most Indian financial reporting stops at "lakh crore" for amounts in the billions and trillions. So while 1 Arab technically equals 1 billion, you'll rarely encounter this terminology in contemporary Indian business or media compared to expressing the same amount as 100 crores.
