📖 Currency Calculator: Definition & Formula
What is a Currency Calculator? A currency calculator converts an amount from one currency to another using the current exchange rate.
Formula Used:
- Converted Amount: Amount × (Rate To / Rate From)
- Exchange Rate: The value of one currency in terms of another
- Cross Rate: Rate between two currencies using USD as base
📌 All rates are expressed as 1 USD = X currency
📝 Example Calculation
Example: Convert 100 USD to EUR (Rate: 1 USD = 0.92 EUR)
Step 1: Identify the exchange rate (1 USD = 0.92 EUR)
Step 2: Multiply amount by rate
Step 3: 100 × 0.92 = 92 EUR
100 US Dollars = 92 Euros
