Hindi numbers 1 to 100: counting, lakh and crore explained

Hindi counts one (एक, ek), two (दो, do), three (तीन, teen), up to ten (दस, das) and a hundred (सौ, sau). Above that it stops grouping in thousands: one lakh (लाख) is 100,000 and one crore (करोड़) is 10,000,000. The numbers between 1 and 100 are largely irregular and have to be learned individually.

English learners usually treat numbers as the easy part of a language. Learn one to ten, learn the tens, and the rest assembles itself: twenty-one, twenty-two, thirty-one. Hindi does not work that way, and this is the first place most self-taught learners quietly give up.

In Hindi, the sound changes in ways you cannot predict from the parts. 21 is इक्कीस (ikkees) and 31 is इकतीस (ikatees) — both mean 'one and the tens', but neither is spelled or pronounced the way the pattern suggests. In practice, the numbers 1 to 100 are close to a hundred separate words.

One to ten

These ten are worth knowing cold, because they turn up inside prices, phone numbers, and dates far more often than anything above twenty.

The tens are the real backbone

Learn these nine and you can already handle most everyday amounts by rounding — पचास रुपये for fifty rupees, सौ रुपये for a hundred. Shopkeepers round to these numbers constantly, so they carry more weight than the exact values in between.

Why the numbers in between are irregular

Hindi puts the unit before the ten, the opposite of English. So 21 is roughly 'one-twenty', not 'twenty-one'. But centuries of spoken shortening have eroded the join, and what survives is a set of forms you have to learn one at a time.

That last group is the pattern worth noticing: numbers ending in 9 are usually built as 'one less than the next ten', not 'nine plus this ten'. It is the one piece of structure hiding in an otherwise irregular list.

Lakh and crore — the part that trips up money

Above a thousand, Indian numbering stops grouping in thousands and millions. It groups in lakhs and crores, and the digit separators move with it.

Machine translation regularly converts लाख to 'lakh' and leaves it there, or worse, renders it as 'million'. If you are reading Indian property or salary figures, do the arithmetic yourself: one lakh is 100,000 and one crore is 100 lakh.

Numbers behave like adjectives

A number sits before the noun, and the noun usually takes its plural form — but the number itself never changes for gender, which makes it one of the few easy corners of Hindi grammar.

For counting people, Hindi often adds लोग (log) or a counter word: तीन लोग for three people. Saying just तीन and stopping sounds clipped, the way 'give me three' does in English.

The Devanagari digits

You will still see the original digits on older signage, in exam papers, and on some government forms, so they are worth recognising even though most printed material now uses 0–9. To type them yourself you need a Devanagari keyboard.

How to actually learn these

• Memorise 1–20 properly. Below twenty there is no shortcut, and these cover most daily use.
• Memorise the nine tens. With those plus 1–20 you can approximate almost any amount.
• Fill in the gaps by use, not by drilling — learn 47 the day you need to say 47.
• Practise with money. Prices are where numbers show up most, and rupee amounts give you instant feedback.
• Learn lakh and crore before anything above 100. You will meet them long before you meet 63.

If a number is critical — a price, an address, a phone number — say it back to the other person. Indian speakers do this routinely among themselves, so repeating a figure to confirm reads as careful, not as poor Hindi.
