1. What is Cross Currency Rate?

A cross currency rate is an exchange rate between two currencies, calculated by using a third currency (usually USD) as a base. It's used when there is no direct exchange rate available between the two currencies in the foreign exchange market.

2. How Does the Calculator Work?

The calculator uses the cross rate formula:

Where:

• \( currency1 \) — First currency's rate against the base currency
• \( base \) — Base currency rate (usually USD)
• \( currency2 \) — Second currency's rate against the base currency

Explanation: The formula calculates how much of currency2 you would get for one unit of currency1, using the base currency as an intermediary.

3. Importance of Cross Rate Calculation

Details: Cross rates are essential in international finance and trade when direct exchange rates aren't available. They're used by banks, businesses, and travelers dealing with multiple currencies.

4. Using the Calculator

Tips: Enter the exchange rates for both currencies against the base currency (typically USD). All values must be positive numbers.
