Common mistakes
- Using 30 ml per ounce for large amounts. The shortcut overshoots by about 1.4 percent, half an ounce per liter.
- Mixing US and UK fluid ounces. The UK imperial ounce is 28.41 ml, so UK labels convert differently.
- Confusing fluid ounces with weight ounces. Fluid ounces measure volume, not how much the liquid weighs.
