To measure ingredients for the recipes, we primarily rely on volumetric measurements as is conventional for recipes in the U.S. In addition, we also provide metric measurements in our recipes. Every effort is made to make accurate measurements and conversions. Since the metric system uses both volumetric measurements (for liquids) and weight measurements (for dry ingredients) we convert liquid ingredient amounts from fluid ounces to milliliters, and we weigh the dry ingredients on a scale to measure them in grams.
N.B.: It is impossible to accurately convert a volumetric measure (e.g. 1/2 cup) of a dry ingredient into its metric weight because the weight of an ingredient will vary depending on its density. One cup of sugar does not weigh the same as one cup of flour, and even then, how densly you pack the flour in your measuring cup will vary its weight. As a result, the weight of 1 cup of an ingredient may vary from kitchen to kitchen (or even day to day in the same kitchen due to things like humidity). For each conversion that provides a U.S. volumetric measure and its equivalent in metric weight, please note that there may be slight variations in the weight (particularly with pulverized ingredients).
For ingredients measured in teaspoons (tsp) and tablespoons (tbsp), these are their approximate equivalents:
1/8 tsp = 0,6 ml
1/4 tsp = 1,25 ml
1/2 tsp = 2,5 ml
1 tsp = 5 ml
1/2 tbsp = 1 1/2 tsp = 7,5 ml
1 tbsp = 3 tsp = 1/2 fl oz = 15 ml
2 tbsp = 1 fl oz = 1/8 cup = 30 ml
16 tbsp = 8 fl oz = 1 cup = 237 ml
