What is Currency Conversion?
Currency conversion is the process of exchanging one currency for another at a specific exchange rate. This is essential for international travel, online shopping, business transactions, and investments across borders.
Whether you're planning a vacation abroad, sending money to family overseas, or investing in foreign stocks, understanding currency conversion helps you get the best value for your money.
Quick Fact
The global foreign exchange (forex) market trades over $6.6 trillion daily, making it the largest financial market in the world. Exchange rates fluctuate constantly based on supply, demand, and economic factors!
Exchange Rates Explained
An exchange rate tells you how much one currency is worth in terms of another. Rates change constantly throughout the day based on market conditions.
Types of Exchange Rates
| Type | Description | Best For |
|---|---|---|
| Mid-Market Rate | Average of buy/sell rates | Reference rate (what we show) |
| Bank Rate | Rate offered by banks | Bank transfers, exchanges |
| Currency Exchange Rate | Rate at exchange bureaus | Travel cash exchanges |
| Credit Card Rate | Rate for card transactions | International purchases |
Important Note
Banks and exchange services typically add a spread of 2-5% to the mid-market rate. This is how they make profit. Always compare rates before exchanging large amounts!

Amount: Original amount in source currency
To Rate: Exchange rate of target currency (vs USD)
From Rate: Exchange rate of source currency (vs USD)

Frequently Asked Questions
Q: Why do exchange rates change?
Exchange rates fluctuate due to supply and demand, economic indicators (GDP, inflation, employment), interest rates, political stability, and market speculation. The forex market operates 24/5, so rates change constantly.
Q: Where can I get the best exchange rates?
Typically: 1) Online money transfer services (Wise, Revolut), 2) Local banks (for customers), 3) ATMs in destination country. Avoid: Airport exchanges and tourist area exchange bureaus (worst rates).
Q: What's the difference between buy and sell rates?
Buy rate: Rate at which exchange service buys your currency (you sell)
Sell rate: Rate at which they sell you currency (you buy)
The difference (spread) is their profit margin.
Q: Should I exchange money before traveling?
It depends. For popular destinations, exchanging a small amount before travel is convenient. For better rates, withdraw from ATMs at your destination or use no-fee credit cards for purchases.
Q: Are exchange rates the same on weekends?
Forex markets are closed on weekends, so rates remain static from Friday close to Sunday open. However, some services may add extra fees for weekend transactions.
Q: What is dynamic currency conversion (DCC)?
DCC allows you to pay in your home currency at foreign merchants. Avoid this! The exchange rate is poor and includes hidden fees. Always choose to pay in local currency for better rates.
