Common mistakes

• Dividing instead of multiplying. A quart is smaller than a liter, so the number of quarts must come out larger: 1 liter = 1.05669 qt.
• 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 1.06 to 1 first puts large values noticeably off.
