Measuring Olive Oil Accurately
Why weight matters: 1/2 cup of olive oil can weigh anywhere from 92g to 130g depending on how you measure it. The USDA standard is 108g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About olive oil density: Olive oil is slightly lighter than vegetable oil. 1 cup = 216g. Extra virgin, virgin, and pure olive oil have the same density. Solidifies in the refrigerator — return to room temperature before measuring.
About 1/2 Cup as a Measurement
1/2 cup (120ml) is the most common single-serving measurement in baking. It equals 8 tablespoons or 24 teaspoons. Most standard muffin recipes call for 1/2 cup of flour per 6 muffins.
Half cup is a standard baking unit used in muffins, quick breads, pancakes, and cookie doughs. It represents exactly half of a US standard measuring cup (240ml).
