💱 Currency Converter

Convert between 35+ major world currencies instantly. Uses approximate static exchange rates — ideal for quick estimates and travel planning.

What is a Currency Converter?

A currency converter calculates the equivalent value of a monetary amount in one currency when expressed in another, based on exchange rates. Exchange rates represent the price at which one currency can be purchased with another — if 1 USD = 83.50 INR, then $100 purchases 8,350 Indian rupees. Currency converters are used daily by travellers, importers, exporters, online shoppers, and investors for budgeting and financial planning across different monetary systems.

Exchange rates are typically quoted relative to a base currency — most often the US dollar. A converter normalises the input amount to USD and then converts to the target currency. For example, to convert British pounds to Japanese yen, the calculation is: GBP ÷ GBP/USD rate = USD equivalent, then USD × JPY/USD rate = JPY result. This two-step cross-rate approach enables conversion between any pair of currencies using a single USD-anchored rate table.

The exchange rates in this converter are static approximations — accurate for quick estimates, travel budgeting, and educational purposes. For actual financial transactions, import/export contracts, or currency purchases, always check live rates from a regulated financial source such as your bank, a fintech app (Wise, Revolut), or a central bank publication. Live rates can differ materially from static estimates due to daily market movements, bid-ask spreads, and transaction fees.

How Currency Conversion Works

Amount in USD = Amount ÷ Rate(From)
Result = Amount in USD × Rate(To)

All rates are stored relative to 1 USD. The converter first normalises your amount to USD, then converts to the target currency.

Frequently Asked Questions

Currency exchange rates fluctuate due to supply and demand in the foreign exchange (forex) market, influenced by interest rates, inflation, political stability, economic performance, and speculative trading. Major rates can change by the second during trading hours.

The mid-market rate (also called interbank rate) is the midpoint between buy and sell prices — the fairest rate. Banks and exchange services add a markup (spread) on top of this, which is how they make money. You will rarely get the exact mid-market rate as a consumer.

No — this converter uses static approximate rates hardcoded at the time of publication. For transactions, always check your bank, a fintech app like Wise or Revolut, or a reputable financial site for live rates.

Forex (foreign exchange) trading is the buying and selling of currencies to profit from rate fluctuations. It is the largest financial market in the world, with over $7 trillion traded daily. Unlike stock markets, forex operates 24 hours a day, 5 days a week.

Use a no-fee travel credit card or a specialist service like Wise, Revolut, or a local ATM in your destination country. Avoid airport exchange booths and hotel desks — they typically offer the worst rates. Never accept dynamic currency conversion (DCC) when offered abroad.

Common Mistakes

1
Not accounting for bid-ask spread
Banks and exchanges apply a 1–3% spread on top of mid-market rates — the actual amount received is always less.
2
Ignoring transaction fees
Wire transfer fees ($15–45) and conversion charges significantly reduce the final amount delivered.
3
Using stale rates for contracts
Exchange rates can move 1–2% per day. For large transactions, use live rates from a regulated provider.
4
Confusing buy vs sell rates
Banks buy foreign currency at a lower rate than they sell — the quoted rate depends on which direction you're converting.
5
Ambiguous currency names
USD, CAD, AUD, NZD are all called "dollars" — always use the ISO 4217 three-letter code to avoid confusion.
