Understanding the Conversion Formula
The currency conversion system works using a simple but effective formula based on USD as a base currency.
Step 1: Convert to USD
All input values are first converted into USD:
USD Value = Amount ÷ Exchange Rate of Source Currency
Step 2: Convert to Target Currency
Then USD is converted into the selected currency:
Final Value = USD Value × Exchange Rate of Target Currency
Example Rates Used:
- 1 USD = 1
- 1 EUR = 0.92 USD
- 1 GBP = 0.78 USD
- 1 PKR = 280 USD (approx base system scaling)
- 1 INR = 83 USD
These values help simulate real-world conversion logic.
Mathematical Operation Formula
The calculator also performs basic arithmetic operations:
Addition
Result = Amount + Second Value
Subtraction
Result = Amount - Second Value
Multiplication
Result = Amount × Second Value
Division
Result = Amount ÷ Second Value
If the second value is zero, the system safely prevents errors.
Example Calculation
Example 1: Currency Conversion
Convert 100 USD to EUR
- USD is base currency
- EUR rate = 0.92
Result:
100 × 0.92 = 92 EUR
Example 2: Calculation Function
Add 100 + 50
Result:
150 USD
Example 3: Combined Use
Convert 200 GBP to USD and multiply by 2
- 200 GBP → USD
- Then × 2
Final result gives both conversion and calculation output.
