How currency exchange rates work

Most countries have their own currency. When people from one country wish to purchase goods and services from another country, they need to engage in currency exchange. The rate at which one currency is exchanged for another is called the exchange rate. Exchange rates are expressed as a ratio of one currency to another. For instance, the exchange rate of US Dollars to Australian Dollars might be expressed as 1.11, to indicate that 1.11 Australian Dollars would be received for the currency exchange of 1 US Dollar.

Most of the time, the currency which is worth more is set as the base currency. For instance, in the example above, the US Dollar is the base currency. It is usually easier to understand bigger numbers than fractions, which is why currency exchange rates are usually quoted in this manner.

Why do currency values fluctuate?

The exchange rates that are quoted worldwide fluctuate almost every second.

The exchange rates that are quoted are dependent on the demand and supply of different currencies. This demand and supply in turn depends on a number of variables, including interest rates, economic conditions and sudden news events. For instance, if the Australian economy is doing very well, Australians will be interested in buying a lot of US products. This means that demand for US Dollars will rise, and 1 US Dollar will start to be worth more Australian Dollars. On the other hand, if the Australian government raises interest rates compared to other nations, foreign individuals will be interested in buying Australian Dollars – this will raise the value of the Australian Dollar.

How to calculate currency conversions

If you wish to convert one currency to another, you should use a currency converter calculator. A currency converter calculator is a type of software that will automatically calculate the value of one currency in terms of another. You can find many different types of currency converter calculators online. Most of them are very simple to use – you simply enter the currency you would like to exchange (for instance, 100 US Dollars), select the currency you wish to convert it to (for instance, Australian Dollars) and hit the “calculate” button. The value is then computed automatically – in this case, you might find that 100 US Dollars are worth 89 Australian Dollars.
