Understanding Currency Exchange Rates
Currency exchange rates represent the value of one country's currency relative to another. These rates fluctuate continuously based on global economic forces, geopolitical events, and market sentiment. Whether you are planning international travel, conducting cross-border business, or investing in foreign assets, understanding how currency conversion works is essential.
Our Currency Converter fetches live exchange rates updated hourly from global financial markets, ensuring you always get the most accurate conversion available. We support over 30 major world currencies, from the US Dollar and Euro to the Romanian Leu and Japanese Yen.
How Exchange Rates Work
Exchange rates are determined by the foreign exchange market (Forex), the largest and most liquid financial market in the world, with over $7.5 trillion in daily trading volume. Rates are influenced by several key factors:
1. Interest Rates
Central banks set interest rates that directly affect currency values. Higher interest rates attract foreign investment, increasing demand for that currency and raising its value. The US Federal Reserve, European Central Bank, and Bank of England decisions are closely watched by currency traders worldwide.
2. Inflation
Countries with lower inflation rates typically see their currencies appreciate over time, as purchasing power increases relative to other currencies. The Consumer Price Index (CPI) is a key indicator traders use to forecast currency movements.
3. Economic Performance
Strong economic indicators — GDP growth, low unemployment, trade surpluses — generally strengthen a currency. Conversely, political instability, recessions, or high debt levels can cause rapid depreciation.

Spot Rate vs. Bank Rate
The rate shown in our converter is the mid-market rate (also called the spot rate or interbank rate) — the midpoint between buy and sell prices used by banks when trading with each other. When you exchange money at a bank or currency exchange, you will typically receive a less favorable rate, as financial institutions add a margin (spread) to profit from the transaction.
For the best rates when traveling, consider using a multi-currency card or a fintech service like Wise or Revolut, which typically offer rates much closer to the mid-market rate than traditional banks.
Currency Codes (ISO 4217)
Every currency in the world is identified by a three-letter ISO 4217 code. For example, USD stands for United States Dollar, EUR for Euro, GBP for British Pound Sterling, and RON for Romanian Leu. These standardized codes are used in international banking, financial systems, and all currency conversion tools worldwide to avoid ambiguity.
Frequently Asked Questions
How often are the exchange rates updated?
Our currency rates are fetched from live financial data sources and cached for up to one hour. This means the rates you see are never more than 60 minutes old, providing a reliable reference for most personal and business needs.
Are the rates the same as at a bank or airport?
No. We display the mid-market rate, which is the purest exchange rate between two currencies. Banks and currency exchange offices add a fee or margin on top of this rate. Airport exchanges typically offer the worst rates. Always compare before exchanging large amounts.
Which currencies does Unitomatic support?
We support 30+ major world currencies including USD, EUR, GBP, RON, JPY, CAD, AUD, CHF, CNY, INR, MXN, BRL, KRW, SGD, HKD, NOK, SEK, DKK, PLN, CZK, HUF, TRY, ZAR, AED, SAR, THB, MYR, IDR, PHP, and NZD.
Why do exchange rates change constantly?
The Forex market operates 24 hours a day, 5 days a week, and rates fluctuate based on supply and demand, economic data releases, central bank decisions, geopolitical events, and trader speculation. Even minutes can make a significant difference for large transactions.
Can I use this converter for business invoicing?
Our converter provides an excellent reference point for business use. However, for official invoicing and accounting purposes, always confirm the rate with your bank or payment processor at the time of the transaction, as rates can change between when you check and when the payment is processed.
