How Cross-Border Fuel Cost Calculator Works?
This tool works by converting a foreign price per liter into US dollars and then into a price per US gallon. The result lets you compare foreign fuel prices with US prices.
Enter the foreign price per liter
Type the local price, for example 1.62 Canadian dollars (CAD) per liter.
Enter the exchange rate
Type the rate to US dollars (USD), for example 0.74 USD per CAD.
Read the normalized price
The tool returns the price in USD per US gallon.
Compare with home prices
Set the result next to your local price per gallon.
Cross-Border Fuel Cost Calculator Formula
The formula is USD per Gallon = Price per Liter × Exchange Rate × 3.78541.
USD per Gallon = Price per Liter × Exchange Rate × 3.78541Formula variables
- Price per Liter
- Foreign pump price in local currency.
- Exchange Rate
- US dollars per 1 unit of local currency.
- 3.78541
- Liters in 1 US gallon.
Worked example
- Foreign Price (e.g. CAD/Liter): 1.62 curr/L
- Exchange Rate to USD: 0.74 rate
- Convert currency: 1.62 × 0.74 = $1.199 USD per liter.
- Convert volume: $1.199 × 3.78541 = $4.54 per US gallon.
Result: 4.54 (Normalized $/gal)
Exchange rates change daily. Banks and card issuers add 1% to 3% in foreign transaction fees, which raises the real price paid.
