Both Google Search and Yahoo! allows you to check current conversion rates of major currencies all over the world. Let’s check out in this post how to do so:

Google Search

Open Google Search in your browser, mobile or tablet device and with a simple query you can check the exchange rates. Suppose you want to know the current exchange rate of 100 US Dollars in Euro, all you need to do is to enter any of the following search terms:

100 USD to Euro (Example) OR 100 USD in Euro (Example)

exchange rate

You will also see a small graph in which you can see previous year exchange rates. The general search query for Currency Conversion in Google is following:

<Amount> <Currency Name> to <Other Currency Name>

Yahoo! Finance

Yahoo! also allows you to check conversion rates in a AJAX based environment. As soon as you land on the converter page, you will see following interface:

yahoo currency

The above interface only works, if you have JavaScript turned on in your browser. In case it is turned off, then you will see a lower version of the converter:

It’s recommended that you should Turn ON JavaScript in your browser for Faster Conversions.

Check Past Exchange Rates

Yahoo! Finance also allows you to check past exchange rates of all major currencies. Suppose you want to know the exchange rate of US Dollar and Indian Rupee on 3rd of December 2012, all you need to do is to select the date from Calendar and you will see the rate on that particular day:

Another way to check past rates and fluctuations is by clicking on View 5 Day trend just below the converter and you will be able to see the rates in graphical format:

historical exchange rates

Following are the things that you can do on this page:

  • Select 1 Day, 5 Days, 3 Months, 1 Year, 2 and 5 Years to see historical exchange rates.
  • Compare the selected currencies with some other currency, S&P 500, Nasdaq and Dow.
  • See previous day closing and current opening values, Asking and Bidding Price and Range for 1 day and 52 weeks.

Overall, Yahoo! will serve you better in case you are fully into finance.

Important Note: These services may give you a close value of current exchange rate, not the exact one. If you are ready to transact in foreign currency, then make sure to check / compare the rates with other sources too. Also, the rates shown on Google and Yahoo! are Bank Rates, not High Street Rates (which may include commissions).
