Field notes
The calculator accepts different units for each price—yen per liter off base and dollars per U.S. gallon on base—and lets users choose a purchase quantity in gallons or liters. Its exchange-rate control points to Frankfurter’s latest daily rates while allowing manual adjustment. Users can log a fill-up after purchase, but the page says history is tied to the browser; the all-location savings total is not populated in this snapshot.
