Lakh Crore Converter - Crores to Millions & Billions

India uses a unique numbering system that can be confusing when comparing figures with international standards.

Reviewed by: CalcMojo Editorial Team

This lakh crore converter instantly translates between the Indian numbering system (hundreds, thousands, lakhs, crores, arab, kharab) and the international system (thousands, millions, billions, trillions), eliminating the mental gymnastics required when reading financial news, global business reports, or comparing currency amounts across systems.

The Indian numbering system groups digits differently after the first three: while the international system continues in groups of three (thousand, million, billion), the Indian system switches to groups of two after the initial thousand (lakh, crore, arab). This means 1 crore (1,00,00,000) equals 10 million (10,000,000) — the same number, just formatted and named differently. The comma placement alone causes confusion for many people working across both systems.

Whether you are reading a company’s annual report that quotes revenue in crores, converting a salary offered in lakhs per annum to understand its international equivalent, comparing Indian GDP figures with global data, or simply trying to make sense of numbers in business news, this converter handles every denomination instantly and accurately.

Understanding the Indian Number System

The Indian number system, also called the South Asian numbering system, is used in India, Pakistan, Bangladesh, Nepal, and Sri Lanka. It shares the same base-10 structure as the international system but groups digits differently after the thousands place.

Indian Number System Denominations:

| Indian Term | Numerical Value | Zeros | International Equivalent | |—|—|—|—| | One | 1 | 0 | One | | Ten | 10 | 1 | Ten | | Hundred | 100 | 2 | Hundred | | Thousand | 1,000 | 3 | Thousand | | Ten Thousand | 10,000 | 4 | Ten Thousand | | Lakh | 1,00,000 | 5 | Hundred Thousand (0.1 Million) | | Ten Lakh | 10,00,000 | 6 | One Million | | Crore | 1,00,00,000 | 7 | Ten Million | | Ten Crore | 10,00,00,000 | 8 | Hundred Million | | Arab | 1,00,00,00,000 | 9 | One Billion | | Ten Arab | 10,00,00,00,000 | 10 | Ten Billion | | Kharab | 1,00,00,00,00,000 | 11 | Hundred Billion | | Ten Kharab | 10,00,00,00,00,000 | 12 | One Trillion | | Neel | 1,00,00,00,00,00,000 | 13 | Ten Trillion |

The comma placement in the Indian system reflects the grouping: the first comma comes after three digits (thousands), and then every two digits thereafter (lakhs, crores, arab, etc.). In the international system, commas appear every three digits consistently.

Quick Reference Conversions

The conversions you will use most frequently:

Lakhs to Millions:

1 Lakh = 0.1 Million (or 100 Thousand)
10 Lakhs = 1 Million
100 Lakhs = 10 Million = 1 Crore

Crores to Millions and Billions:

1 Crore = 10 Million
10 Crores = 100 Million
100 Crores = 1 Billion = 1 Arab

Arab and Kharab to Billions and Trillions:

1 Arab = 1 Billion
10 Arab = 10 Billion
1 Kharab = 100 Billion
10 Kharab = 1 Trillion

The Key Formula:

To convert lakhs to millions: divide by 10. To convert crores to millions: multiply by 10. To convert crores to billions: divide by 100.

Examples:

₹5 lakh = ₹0.5 million = ₹500,000
₹25 crore = ₹250 million = ₹25,00,00,000
₹4,500 crore = ₹45 billion = ₹45,00,00,00,000

Why India Uses a Different Number System

The Indian numbering system has roots in ancient Indian mathematics dating back thousands of years. The Vedic and Sanskrit mathematical traditions developed a comprehensive naming system for large numbers well before the international system was standardized.

Historical Context:

Ancient Indian mathematicians created names for extremely large numbers. The Yajurveda (circa 1200 BCE) contains references to powers of ten up to 10^12. The Buddhist text Lalitavistara mentions numbers up to 10^53. This rich mathematical heritage led to a numbering convention that persisted through centuries and remains in daily use across South Asia.

Practical Reasons for Continued Use:

The Indian system persists because it is deeply embedded in daily life, government, media, and commerce. Government budgets are presented in crores, company results are reported in lakhs and crores, property prices are quoted in lakhs, and salary discussions happen in lakhs per annum. Switching to the international system would require rewiring how 1.4 billion people think about and discuss numbers — a change unlikely to happen regardless of globalization.

The Comma Placement Convention:

The Indian comma system (1,00,000 instead of 100,000) directly reflects the two-digit grouping beyond thousands. This is not an error or quirk — it is a consistent mathematical convention. Indian financial documents, government gazettes, and legal contracts all follow this convention. Understanding the comma placement is the fastest way to read Indian numbers correctly.

Converting Indian Financial Figures

Financial numbers in India are almost always quoted in lakhs or crores, even in contexts where international equivalents would be more intuitive. Here is how to quickly navigate common scenarios.

Salary Conversions:

Indian salaries are typically quoted as LPA (Lakhs Per Annum):

5 LPA = ₹5,00,000 = ₹500,000 per year = approximately ₹41,667 per month
12 LPA = ₹12,00,000 = ₹1,200,000 per year = approximately ₹1,00,000 per month
25 LPA = ₹25,00,000 = ₹2,500,000 per year = approximately ₹2,08,333 per month
1 Crore per annum = ₹1,00,00,000 = ₹10,000,000 per year = approximately ₹8,33,333 per month

When comparing with international salaries, convert to USD or the relevant currency: ₹25 LPA at 83 INR/USD is approximately $30,120 per year or $2,510 per month.

Company Revenue and Market Cap:

Indian business news reports revenue and market capitalization in crores:

₹500 crore revenue = ₹5 billion = approximately $60 million (at 83 INR/USD)
₹10,000 crore market cap = ₹100 billion = approximately $1.2 billion
₹1 lakh crore = ₹1 trillion = approximately $12 billion

India’s GDP of approximately ₹300 lakh crore equals approximately $3.6 trillion.

Real Estate:

Property prices in India are quoted in lakhs or crores:

₹45 lakh flat = ₹45,00,000 = ₹4.5 million
₹1.2 crore house = ₹1,20,00,000 = ₹12 million
₹5,000 per square foot for a 1,000 sq ft flat = ₹50 lakh = ₹5 million

When evaluating property with an EMI Calculator, ensure you enter the amount in the correct denomination.

The Comma Placement Guide

The most practical aspect of the Indian numbering system is understanding where the commas go.

Indian Comma Placement Rules:

First comma after 3 digits from the right (separating thousands)
Every subsequent comma after 2 digits

Examples:

10,000 (ten thousand) — same in both systems
1,00,000 (one lakh) = 100,000 (one hundred thousand)
10,00,000 (ten lakhs) = 1,000,000 (one million)
1,00,00,000 (one crore) = 10,000,000 (ten million)
1,00,00,00,000 (one arab) = 1,000,000,000 (one billion)

Reading Large Indian Numbers:

When you see 35,42,18,76,000, read it as: 35 arab, 42 crore, 18 lakh, 76 thousand. In international terms: 35.42 billion or 35,421,876,000.

A useful trick: count the commas in the Indian format. Two commas = lakhs range. Three commas = crores range. Four commas = arab range.

Number Words in Indian Languages

The Indian number system has equivalent terms across multiple Indian languages, all following the same grouping convention:

Hindi: Hazaar (thousand), Lakh, Crore, Arab, Kharab, Neel, Padma, Shankh Tamil: Ayiram (thousand), Latcham (lakh), Kodi (crore) Bengali: Hajar (thousand), Lakh, Koti (crore) Marathi: Hazaar, Lakh, Koti (crore)

The terms lakh and crore are used in English as well when communicating about Indian financial matters. International publications covering India (Financial Times, Bloomberg, Reuters) increasingly use these terms with parenthetical international equivalents for their global audience.

Tools and Tips for Quick Mental Conversion

The "Move the Decimal" Method:

Lakhs to millions: move decimal one place left. 50 lakhs = 5.0 million
Crores to millions: move decimal one place right. 5 crores = 50 million
Crores to billions: move decimal two places left. 500 crores = 5.0 billion

The "Divide/Multiply by 10" Shortcut:

Lakhs / 10 = Millions (7 lakhs / 10 = 0.7 million)
Crores x 10 = Millions (3 crores x 10 = 30 million)
Crores / 100 = Billions (250 crores / 100 = 2.5 billion)

For Currency Conversion (INR to USD at ~83):

₹1 lakh = approximately $1,200
₹1 crore = approximately $120,000
₹100 crore = approximately $12 million
₹1,000 crore = approximately $120 million

These are approximate and depend on the current exchange rate, but they serve as useful mental benchmarks.

Frequently Asked Questions

How many lakhs make one million?

10 lakhs equal 1 million. One lakh (1,00,000) is 100,000, and one million is 1,000,000. To convert lakhs to millions, divide by 10. For example, 25 lakhs = 2.5 million.

How many crores make one billion?

100 crores equal 1 billion. One crore (1,00,00,000) is 10 million, and one billion is 1,000 million. To convert crores to billions, divide by 100. For example, 350 crores = 3.5 billion.

What is 1 lakh in international terms?

1 lakh equals 100,000 (one hundred thousand) or 0.1 million. In the Indian notation, it is written as 1,00,000 with the comma after the first digit. The term lakh originates from Sanskrit and is used across South Asia.

Why does India use lakhs and crores instead of millions and billions?

The Indian numbering system has roots in ancient Vedic and Sanskrit mathematics, predating the standardized international system by millennia. It is deeply embedded in Indian culture, government, media, and daily commerce. All Indian financial regulations, government budgets, and business reporting use lakhs and crores.

How do I read Indian numbers with their comma placement?

In the Indian system, the first comma comes after 3 digits from the right (thousands), then every 2 digits. So 1,00,00,000 is one crore. Count the commas: 2 commas = lakhs range, 3 commas = crores, 4 commas = arab (billion). Read from left: each two-digit group names the next denomination.

What comes after crore in the Indian number system?

After crore (10^7), the sequence is: Arab (10^9, equal to 1 billion), Kharab (10^11, equal to 100 billion), Neel (10^13, equal to 10 trillion), Padma (10^15), and Shankh (10^17). In practice, arab and kharab are occasionally used, while neel and beyond are mostly theoretical.

How do I convert Indian salary (LPA) to monthly income?

Divide the LPA figure by 12. For example, 12 LPA = ₹12,00,000 per year = ₹1,00,000 per month (before tax and deductions). Note that LPA is the gross annual salary; your actual take-home will be lower after tax, PF, and other deductions.
