If you need an offline or currency table that you can use for your currency estimation calculator, or you want to learn the currency of countries in the world, you can use my excel currency calculator. It consist of more than 140 currencies value that normalized against 1 US Dollar. So, it will be easy to convert and calculate currencies among them.
This excel spreadsheet consist of two worksheet. The first worksheet is the calculator worksheet that will convert and calculate any amount from any currency to the amount of currency you expect. You can see the result in the blue cell. The second worksheet is the currency table. This table used as a reference table for the first worksheet and also can be used to learn currency name of countries around the world. You can add unavailable currency in this table, but remember to normalized against 1 USD.
I plan to make a real time currency converter, but probably it will be available in next version. Just for reminder, you this as estimation reference, not real reference because the value is changing everytime and different in each country. You must update it every time if you want to use it regularly. You can download the file here.
