## About Cross Exchange Rate Calculator (Formula)

A **Cross Exchange Rate Calculator** is a valuable tool for anyone dealing with foreign exchange transactions. It allows users to determine the exchange rate between two currencies when they are not directly quoted against each other. For example, if you want to know how many euros you can get for a specific amount of British pounds, you can use this calculator to derive the rate using a third currency, like the US dollar, as a reference. Understanding cross exchange rates is essential for traders, travelers, and businesses engaged in international transactions.

### Formula

To calculate the exchange rate of currency A to currency B using a third currency C, use the following formula:

Exchange rate of A to B = Exchange rate of A to C / Exchange rate of B to C.

### How to Use

**Identify the Currencies:**

Determine the three currencies involved in the exchange (A, B, and C).**Find the Exchange Rates:**

Obtain the current exchange rates for currency A to currency C and currency B to currency C. These rates can typically be found on financial news websites or currency exchange platforms.**Apply the Formula:**

Insert the exchange rates into the formula to calculate the cross exchange rate from A to B.**Interpret the Results:**

The resulting value will tell you how much of currency B you can get for one unit of currency A.

### Example

Let’s say you want to find out the cross exchange rate from British Pounds (GBP) to Japanese Yen (JPY) using the US Dollar (USD) as a reference currency.

**Step 1:**

Suppose the exchange rate of GBP to USD is 1.35, and the exchange rate of JPY to USD is 0.0091.**Step 2:**

Now, apply the formula:

Exchange rate of GBP to JPY = Exchange rate of GBP to USD / Exchange rate of JPY to USD.

Exchange rate of GBP to JPY = 1.35 / 0.0091 ≈ 148.35.

This means that 1 British Pound is approximately 148.35 Japanese Yen.
