**So many Indian rupees are how many American dollars?**

The United States dollar (ISO 4217 Code USD) with symbol $ or US$, is subdivided into 100 cents (singular cent), and is the currency of the United States of America.

The Indian rupee (ISO 4217 Code INR) with symbol Rs., is subdivided into 100 paise (singular paisa), and is the currency of India.

Due to increasing economic transactions between USA and India, it is common for Americans to often ask so many Indian rupees are how many American dollars and likewise for Indians to often ask so many American dollars are how many Indian rupees. The answer to such vital questions depends on the Indian number system and the current exchange rates.

**The Indian number system**

Hindi Transliteration = Figure = Words = Power notation

Ek = 1 = One = 10^{0}

Dus = 10 = Ten = 10^{1}

Sau = 100 = Hundred = 10^{2}

Hazaar or Sahasr = 1,000 = One thousand = 10^{3}

Dus Hazaar = 10,000 = Ten thousand = 10^{4}

Lakh = 1,00,000 = One hundred thousand = 10^{5}

Dus Lakh = 10,00,000 = One million = 10^{6}

Crore = 1,00,00,000 = Ten million = 10^{7}

Dus Crore = 10,00,00,000 = One hundred million = 10^{8}

Arawb = 1,00,00,00,000 = One billion = 10^{9}

Dus Arawb = 10,00,00,00,000 = Ten billion = 10^{10}

Kharawb = 1,00,00,00,00,000 = One hundred billion = 10^{11}

Dus Kharawb = 10,00,00,00,00,000 = One trillion = 10^{12}

Neel = 1,00,00,00,00,00,000 = Ten trillion = 10^{13}

Dus Neel = 10,00,00,00,00,00,000 = One hundred trillion = 10^{14}

Padma = 1,00,00,00,00,00,00,000 = One quadrillion = 10^{15}

Dus Padma = 10,00,00,00,00,00,00,000 = Ten quadrillion = 10^{16}

Shankh = 1,00,00,00,00,00,00,00,000 = One hundred quadrillion = 10^{17}

Dus Shankh = 10,00,00,00,00,00,00,00,000 = One quintillion = 10^{18}

Mahashankh = 1,00,00,00,00,00,00,00,00,000 = Ten quintillion = 10^{19}

Note: In commercial transactions, the higher numbers above Crore are not used, instead lakh and crore is repeated. For example, for one billion instead of saying Ek Arawb, generally Ek Sau Crore or One hundred Crore is said.

**The exchange rate**

The worth of one currency with respect to another currency is specified by the foreign exchange rate, which is also known as the exchange rate, FX rate or forex rate. The exchange rate is volatile as the market forces of demand and supply influence it. There are different types of exchange rates like spot exchange rates, forward exchange rates, fixed exchange rates, linked exchanges rates, nominal exchange rates, real exchange rates, bilateral exchange rates, effective exchange rates, to name a few. In this article by the term “exchange rate”, only spot exchange rate is to be understood. Spot exchange rate is the current exchange rate. For example, an exchange rate of Rs.47.72 to US$1 means that INR 47.72 is equivalent in worth to USD 1.

Assuming an exchange rate of Rs.45 to US$1, we can arrive at the following:

US$ 1 = 45 x 1 = Rs. 45

US$ 10 = 45 x 10 = Rs. 450

US$ 100 = 45 x 100 = Rs. 4,500

US$ 1,000 = 45 x 1,000 = Rs. 45,000

– – –

US$ One million = 45 x 10,00,000 = Rs. 450,00,000 or Rs. 450 lakhs.

Therefore, we see US$ 1 million at an assumed exchange rate of Rs.45 to US$1 is worth Rs.450 lakhs.

**Conclusion**

With the knowledge of the Indian number system and the prevailing exchange rate at the time of conversion, any amount in USD can be converted into INR and vice versa. To know the current exchange rate, type “currency converter” in any search engine, and numerous currency converters can be found, which can give updated rates and facilities to convert any currency into any other currency of the world.
