Frequently asked questions
How many crores are in 1 billion?
1 billion equals 100 crore, which is the same as 1 arab.
What is the formula to convert billion to crore?
Crores = billions × 100. For example, 5 billion = 500 crore.
Why do India and Pakistan count in lakhs and crores instead of millions?
South Asia uses a numbering system where units advance every two digits after a thousand — lakh (10⁵), crore (10⁷), arab (10⁹), kharab (10¹¹) — while the international system advances every three digits (thousand, million, billion). Both describe the same values; only the grouping and unit names differ.
Is this converter exact for very large numbers?
Yes. All arithmetic uses arbitrary-precision integers (never floating point), so conversions are digit-for-digit exact up to 60 digits — far beyond a shankh (10¹⁷).
