A mid-size sedan with a 16-gallon tank holds 60.57 liters — a common comparison point for European car shoppers. Large American SUVs with 26-gallon tanks hold 98.4 liters, significantly more than European equivalents. In cooking and recipe sharing, American large-batch recipes state volumes in gallons. A 2-gallon stock recipe is 7.57 liters; a 1-gallon marinade bucket is 3.79 liters. Food service recipes (for catering) regularly use gallons. For water consumption and environmental context, Americans measure water usage in gallons. The average American uses 80–100 gallons (303–379 liters) of water per day. A 10-minute shower uses about 25 gallons (94.6 liters). Translating these figures to liters makes them comparable to global per-capita usage statistics. Wine and spirits bottling uses liters globally, but American distribution sometimes uses gallons: a wine barrel holds 59 US gallons (223.3 liters).
