South Asian and international numbering
The South Asian (Pakistani / Indian) system groups digits as the last three, then in pairs — 1,25,00,000 — and names the places thousand (hazaar), lakh, crore, arab, and kharab. The international system groups in threes — 12,500,000 — and names them thousand, million, billion, and trillion. This tool converts a value between the two and shows every representation at once.
A lakh is not a decimal fraction of a million. One lakh equals 100,000, which is 0.1 million. The number is the same; only the unit label and grouping change.
Exact definitions
- 1 thousand = 1,000
- 1 lakh = 100,000 = 0.1 million
- 1 million = 1,000,000 = 10 lakh
- 1 crore = 10,000,000 = 10 million
- 1 arab = 100 crore = 1 billion = 1,000,000,000
- 1 kharab = 100 arab = 100 billion = 100,000,000,000
- 1 trillion = 1,000,000,000,000 = 100 arab = 1 kharab

FAQ
Is 1 lakh equal to 0.1 million?
Yes as a value: 1 lakh = 100,000 = 0.1 million. “Lakh” is a unit name for 100,000, not a fractional unit — the tool always shows the exact number alongside the words.
How many lakh is a million? How many crore is a billion?
1 million = 10 lakh. 1 billion = 100 crore = 1 arab. 1 trillion = 1 lakh crore = 100 arab = 1 kharab.
Does it handle very large numbers?
Yes. The integer part is handled with BigInt, so large values are not rounded or shown in scientific notation. Decimal inputs are shifted digit-by-digit rather than with floating-point maths, so you never see artefacts like 0.30000000000000004.
What unit spellings are recognised?
thousand / hazaar / hazar / k; lakh / lakhs / lac / lacs; crore / crores / cr; arab; kharab; million / mn / m; billion / bn; trillion / tn. Matching is case-insensitive.
