Understanding the Conversion Formula
This calculator uses a simple exchange rate formula based on USD as a base currency.
Step 1: Convert to Base Currency (USD)
- USD is used as the reference currency
- All currencies are first converted into USD
Formula:
USD Value = Amount ÷ Exchange Rate of Source Currency
Step 2: Convert to Target Currency
Once the value is in USD, it is converted to the target currency:
Final Value = USD Value × Exchange Rate of Target Currency
Example Calculation
Let’s understand with an example:
Example:
Convert 100 EUR to INR
Step 1: Given Rates
- 1 USD = 1
- 1 EUR = 0.92 USD
- 1 INR = 83 USD (demo rate system)
Step 2: Convert EUR to USD
100 EUR ÷ 0.92 = 108.70 USD
Step 3: Convert USD to INR
108.70 × 83 = 9022.10 INR
Final Result:
👉 100 EUR ≈ 9022.10 INR
