Converting Volume Measures

Confusion often arises between weight and volume measures when ounces are the unit of measure.

It is important to remember that weight is measured in ounces (oz) and volume is measured in fluid ounces (fl oz). A standard volume measuring cup is equal to 8 fl oz, but the contents of the cup may not always weigh 8 oz/227 g. One cup (8 fl oz/240 mL) of shredded fresh coconut weighs just under 3 oz/84 g, but 1 cup (8 fl oz/240 mL) of peanut butter weighs 9 oz/255 g. Since measuring dry ingredients by weight is much more accurate, it is the preferred and most common method used for measuring dry ingredients in professional kitchens and bakeshops.
