In this article I will be demonstrating ** how to get the formula** which

**converts one type of currency into another and vice versa**. It's a pretty simple task, so let me get started...

Let's say today 0.77 pounds is equal to 1 dollar. How would we be able to get 1 pound in terms of dollars?

Well, what we could do is name the currencies and also the value 0.77:

**Currency 1 = C_1 = 1 Dollar**

**Currency 2 = C_2 = 1 Pound**

**Real Number = r = 0.77**

So, I said that 0.77 pounds is equal to 1 dollar. Because of the definitions above, it can be written like this:

**C_1 = r*C_2**

If we want to make the **opposite conversion**, we do a simple manipulation of the formula above:

**C_2 = (1/r)*C_1**

In __non-mathematical terms__, that would mean that:

**1 Pound = (1/0.77)*(1 Dollar)**

Therefore:

**1 Pound = 1.30 Dollars (to 2 decimal places)**

See, I told you it was pretty simple. You can use the formulas listed here to convert any two currencies back and forth. Just name **C_1** and **C_2** and the multiplier **(r)**.
