Open a Pakistani or Indian news article about a government budget and you'll likely read something like "the project cost 50 crore rupees." If you grew up with the Western thousand/million/billion system, that number is meaningless without translation. This article explains exactly what it means — and why South Asia counts differently in the first place.

The two systems side by side

The Western system groups digits in threes: thousand (10³), million (10⁶), billion (10⁹), trillion (10¹²). The South Asian system groups the first three digits together, then groups everything after that in pairs of two:

ValueWesternSouth Asian
10²HundredSau (सौ)
10³ThousandHazaar (हज़ार)
10⁵Hundred thousandLakh
10⁷Ten millionCrore
10⁹BillionArab
10¹¹Hundred billionKharab

Notice that lakh and crore don't line up neatly with million and billion — a lakh is 100,000 (not a round million), and a crore is 10,000,000 (not a round billion). This is exactly why direct translation trips people up.

Where does this system come from?

The lakh-crore system has roots in ancient Indian mathematics, dating back over 2,000 years to Sanskrit numerical texts. Large number naming conventions appear in early Indian literature and religious texts, where enormous quantities (like grains of sand, or cosmic timescales) needed concise names.

The word "lakh" derives from the Sanskrit lakṣa, and "crore" from koṭi. These terms spread across the Indian subcontinent through Hindi, Urdu, Bengali, Punjabi, and other regional languages, and were later adopted into South Asian English during the colonial period — which is why they're used in English-language news, finance, and government documents throughout Pakistan, India, Bangladesh, Nepal, and Sri Lanka today.

How the comma placement works

This is the part that confuses people who are used to Western formatting. In the South Asian system, only the last three digits are grouped together; everything before that is grouped in pairs:

Both represent the exact same number — twelve million, three hundred forty-five thousand, six hundred seventy-eight (or, in South Asian terms, one crore twenty-three lakh forty-five thousand six hundred seventy-eight). Only the comma placement and the names differ.

A handy shortcut: 10 lakh = 1 million, and 1 crore = 10 million. If you memorize just these two equivalences, you can mentally convert most everyday figures.

Where you'll encounter this system

A note on "arab" — a regional variation

There's a subtlety worth knowing: while lakh (10⁵) and crore (10⁷) are used consistently across South Asia, the exact value of "arab" varies slightly by convention and context. Most commonly, 1 arab = 100 crore = 10⁹ (one billion), aligning arab with the Western billion. This is the convention used throughout this article and in our conversion tool.

Why this matters for everyday accuracy

Mixing up these systems isn't just a curiosity — it has real consequences. A property listed at "85 lakh" is 8,500,000 rupees, not 850,000. A budget line of "200 crore" is 2,000,000,000, not 200,000,000. For anyone working across borders — in finance, real estate, journalism, or international business — knowing both systems fluently (and being able to convert instantly) genuinely matters.

If you regularly need to convert between the two systems, our Number to Words tool displays both formats simultaneously for any number you enter, including the word form and cheque formatting for both Pakistani Rupees and Indian Rupees.
