The History of Indian Currency and Numbering Units: Paisa, Rupee, Lakh and Crore Explained

India has a fascinating history of money, mathematics and numerical systems. Words such as rupee, paisa, anna, lakh, crore and hazaar are part of everyday conversations. Whether discussing salaries, property prices, business transactions or household expenses, Indians regularly use these terms without necessarily knowing where they originated.

However, these familiar words have centuries of history behind them. Some have roots in Sanskrit and Prakrit, while others entered Indian languages through Persian influence and historical trade. India’s numbering system also reflects a remarkable mathematical tradition that developed long before modern banking and financial institutions.

Let’s explore the origins and evolution of these commonly used Indian terms through some interesting questions and answers.

1. Where Did the Word Rupee Originate?

The word rupee has its roots in the Sanskrit word Rūpya (रूप्य), which referred to wrought or worked silver. Its linguistic origin is associated with the Sanskrit word Rūpa, meaning form, appearance or shape.

India has a long history of metallic currency. Silver punch-marked coins were circulating in parts of the subcontinent as early as the sixth century BCE. These coins were used for trade and commercial transactions.

However, the modern rupee is particularly associated with Sher Shah Suri, who ruled large parts of northern India between 1540 and 1545 CE. He introduced a standardised silver coin known as the Rupiya, weighing approximately 11.5 grams.

The Mughal rulers subsequently continued the use of the rupee, and the British administration eventually established it as India’s principal currency.

2. How Did Paisa Become India’s Smallest Currency Unit?

The word paisa has a long history in the Indian monetary vocabulary. It is associated with the older term pice, which was used for small-value copper coins.

Before India adopted decimal currency, the rupee was divided into 16 annas. Each anna was further divided into four pice, while each pice contained three pies.

Consequently, one rupee consisted of 64 pice or 192 pies.

India adopted the decimal currency system on April 1, 1957. Under this system, one rupee was divided into 100 naye paise. The word naye, meaning new, was eventually dropped in 1964, leaving the familiar term paisa.

This change made monetary calculations considerably simpler.

3. What Is the Origin of the Word Lakh?

Lakh is derived from the Sanskrit word Lakṣa (लक्ष), which represents the number 100,000.

It is one of the most distinctive features of the Indian numbering system. Unlike the international system, which generally uses thousands and millions, India traditionally expresses large quantities through thousands, lakhs and crores.

For example:

• 1 lakh = 100,000
• 5 lakh = 500,000
• 10 lakh = 1,000,000
• 50 lakh = 5,000,000

The term lakh is also used in several languages outside India, reflecting the influence of Indian trade and cultural interactions.

4. Where Did the Word Crore Come From?

The word crore evolved from the Sanskrit term Koṭi (कोटि), which represented a large numerical quantity, commonly associated with ten million in the modern Indian numbering system.

One crore equals 100 lakh or 10 million.

The Indian numbering system makes it convenient to express large financial values without using lengthy strings of zeros.

For instance:

• 1 crore = 1,00,00,000
• 10 crore = 10,00,00,000
• 100 crore = 1,00,00,00,000

Interestingly, ancient Indian mathematical and literary traditions also contained names for numbers considerably larger than crore. Terms such as arbuda, kharva, nikharva and padma appeared in different numerical traditions.

5. Why Do Indians Use Hazaar Instead of Sahasra?

Hazaar (हज़ार) is derived from the Persian word Hazār, meaning one thousand.

The word became part of everyday Indian vocabulary through centuries of Persian cultural, administrative and commercial influence.

However, Sanskrit already had its own word for one thousand: Sahasra (सहस्र).

Both words have the same numerical meaning but different linguistic origins.

Persian influenced many aspects of Indian vocabulary, particularly in administration, literature, poetry and everyday communication. Hazaar is one example of this linguistic exchange.

6. What Were Anna, Pice and Pie in the Old Indian Currency System?

Before decimalisation, India’s currency system was based on a combination of rupees, annas, pice and pies.

The traditional arrangement was:

• 1 rupee = 16 annas
• 1 anna = 4 pice
• 1 pice = 3 pies
• 1 rupee = 192 pies

Anna was a major subdivision of the rupee. The term is commonly associated with the Sanskrit word Aṃśa, meaning a part or share.

Pice referred to small copper denominations, while pie represented an even smaller monetary unit.

These denominations were gradually discontinued following the introduction of decimal currency in 1957.

7. What Was the Dam Introduced by Sher Shah Suri?

Dam was a copper coin associated with the monetary reforms of Sher Shah Suri.

His monetary system used three principal metallic denominations: gold, silver and copper. The silver rupiya became particularly influential and helped establish a more standardised monetary framework.

The dam was used for smaller transactions, making it an important component of everyday commerce.

Sher Shah’s monetary reforms influenced subsequent Indian currency systems, including those under the Mughals.

8. Why Does India Use Lakhs and Crores Instead of Millions and Billions?

India follows a distinctive numbering convention in which large numbers are grouped differently from the international system.

The first three digits are grouped from the right, and subsequent digits are grouped in pairs.

For example:

Indian system: 12,34,56,789

International system: 123,456,789

The Indian number is read as twelve crore, thirty-four lakh, fifty-six thousand, seven hundred and eighty-nine.

This convention is deeply established in Indian banking, accounting, taxation, business and everyday communication.

Although international financial institutions frequently use millions and billions, lakhs and crores remain the preferred expressions in domestic transactions.

9. Did Indian Currency and Numbering Words Influence Other Countries?

Yes. India’s historical trade connections and cultural interactions helped spread several words beyond the subcontinent.

The Indonesian currency is called the rupiah, sharing its linguistic ancestry with the Indian rupee.

The English word lakh also comes from Indian linguistic usage. Similarly, the Swahili word laki means one hundred thousand.

These examples demonstrate how commercial relationships and cultural exchanges can influence languages across geographical boundaries.

10. How Did India’s Ancient Mathematical Traditions Influence Modern Counting?

India made significant contributions to mathematics, particularly through the development and transmission of the decimal place-value system and the use of zero.

The Indian numeral system eventually travelled westwards through scholarly exchanges and became the foundation of the Hindu-Arabic numeral system used internationally today.

Ancient Indian mathematical texts also explored extremely large numerical quantities, demonstrating an interest in expressing numbers far beyond ordinary commercial requirements.

The continued use of lakh and crore is another reminder of how historical numerical traditions survive in modern society.

Conclusion

The words paisa, rupee, anna, lakh, crore and hazaar are much more than everyday financial expressions. They represent different periods of India’s linguistic, commercial and mathematical history.

While the rupee developed through ancient monetary traditions and the reforms of successive rulers, lakh and crore reflect India’s longstanding numerical vocabulary. Persian influence introduced words such as hazaar, while decimalisation transformed the country’s monetary calculations.

The next time someone discusses a salary of ₹15 lakh, a property worth ₹2 crore or a business earning thousands of rupees, they are unknowingly using expressions that carry centuries of history.

India’s everyday language continues to preserve an extraordinary connection between its ancient past and modern economic life.
