Troubleshooting
Confusing US and UK (imperial) fluid ounces and gallons
Solution
1 US fluid ounce = 29.574 ml. 1 UK fluid ounce = 28.413 ml. 1 US gallon = 3.785 L. 1 UK gallon = 4.546 L. This converter uses US customary units.
Confusing fluid ounces (volume) with ounces (weight)
Solution
Fluid ounces (fl oz) measure volume. Ounces (oz) measure weight. They are different units and cannot be directly converted without knowing the density of the liquid.
Applying volume conversion to weight in cooking
Solution
Cups and tablespoons measure volume. The weight in grams of 1 cup varies by ingredient density. For baking precision, use a kitchen scale rather than volume measures.
