Converting 28 liters gives 7.396817466 gal. One multiplication does it — 28 × 0.2641720524 = 7.39681746603 US gallons — and because the factor is defined rather than measured, that answer will not drift over time.
28 litres is 7.397 US gallons and 6.159 imperial gallons. In a car averaging 7 L/100 km it is about 400 km of range; as drinking water at the 2 litres a day figure, 14 days.
The result sits 0.3968 gal past 7 gal, so if you need a round figure to quote, 7 gal is the honest nearest one. Plenty of people do this in their head: divide by 3.8 instead of using the exact factor 0.2641720524. At 28 that shortcut gives 7.3684211 US gallons, off by 0.0284 US gallons or about 0.38%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
