Target Amount = Base Amount × Direct Exchange Rate (From Currency ⟶ To Currency)
Inverse Rate = 1 / Direct Exchange Rate

Converts source currency into USD baseline equivalent, then scales by target currency exchange rate multiplier.

Variable Descriptions

Base Amount: The monetary quantity to convert
Direct Rate: The price of one unit of source currency in terms of target currency
Inverse Rate: The reciprocal price of target currency in terms of source currency

Practical Walkthrough

Worked Example

Step 3: Inverse rate = 1 ÷ 0.8950 = 1.1173 USD per 1 EUR.
