Grams and ounces are metric units of mass (weight) to measure ingredients with precision.
They are more accurate than units of volume (i.e. cups, tablespoons & teaspoons) because it doesn’t take into account different densities, like how tightly ingredients are packed into a cup or the shape of chopped ingredients, for example. That’s why professional chefs use mass measurements for consistency in the flavor & look each time a recipe is prepared. To measure with grams or ounces, you need a kitchen scale to weigh the food.
All my recipes are based on grams. If you prefer to measure in American units of volume (i.e. cups, tablespoons & teaspoons), you’ll find the most important ingredients converted below. As mentioned, volume-to-mass conversions are not absolute and each conversion is based on my experience.
Units of mass are more accurate than units of volume
When it comes to measuring ingredients by volume, it is better to use them for fluid ounces because they are always the same. To begin converting fluid ounces, you should know that the volume of 1 milliliter (mL) of pure water at temperature 4 °C = 1 gram (g). Meaning: 1 milliliter = 1 gram.
1 US cup (c) of water = 240 milliliters (mL) or 240 grams (g).
Note: 1 US cup (c) of water = 236.588237 mL and is rounded to precisely 240 mL by US federal regulations (FDA) for food labeling purposes and is standard practice for conversions.
1 US cup (c) of water = 16 US tablespoons (tbsp) or 48 US teaspoon (tsp) or 8 US fluid ounce (fl oz)

Note: Fluid ounces and ounces are different. Fluid ounces are used to measure the volume of liquid ingredients and ounces are used to measure mass.
