This calculator automatically extracts and converts currency values from text input. It's useful for processing financial documents, chat logs, or any text containing monetary amounts.
How It Works
The calculator uses regular expressions to identify currency patterns in text. It supports multiple currency symbols and formats, including:
- Dollar amounts: $100, $1,000.50, 100 USD
- Euro amounts: €50, 50 EUR, 50,00 €
- Pound amounts: £25, 25 GBP, 25.50 GBP
- Yen amounts: ¥1000, 1000 JPY
- Generic currency codes: 100 CAD, 50.50 CHF
The extracted amounts are then converted to the target currency using current exchange rates.
Formula Used
For each currency amount found in text:
1. Extract the numeric value and currency code
2. Convert to base currency (USD) if needed
3. Apply target currency conversion rate
4. Sum all converted amounts
The conversion formula is:
Converted Amount = (Extracted Amount × Exchange Rate) / Base Rate
Worked Example
Consider this text input:
"The total cost is $150.50 and €75. We also have 100 CAD in inventory."
The calculator would:
- Extract $150.50 (USD), €75 (EUR), and 100 CAD
- Convert all to USD using current exchange rates
- Sum the converted amounts
Assuming current rates: 1 EUR = 1.10 USD, 1 CAD = 0.75 USD
Total = ($150.50 × 1) + (€75 × 1.10) + (100 CAD × 0.75)
Total = $150.50 + $82.50 + $75.00 = $308.00
