Common mistakes

• Dividing instead of multiplying. A fluid ounce is smaller than a liter, so the number of fluid ounces must come out larger: 0.5 liters = 16.907 fl oz.
• Mixing fluid ounces with weight ounces. A fluid ounce is a volume (29.57 ml); an ounce on a kitchen scale is a weight (28.35 g). A cup of flour is 8 fl oz by volume but only about 4.25 oz by weight.
• Using the imperial (UK) unit. This page uses US measures. An imperial gallon is 4.546 L (20% more than a US gallon), an imperial pint 568 ml and an imperial fluid ounce 28.41 ml.
• Rounding too early. Keep the full factor until the last step; rounding 33.8 to 34 first puts large values noticeably off.
