Measuring Olive Oil Accurately

Why weight matters: 1/3 cup of olive oil can weigh anywhere from 61g to 86g depending on how you measure it. The USDA standard is 72g (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 1/3 Cup as a Measurement

1/3 cup = 5 tablespoons + 1 teaspoon = 80ml. This unusual fraction appears in recipes that scale for 2 servings from a 3-serving base. It cannot be made from combining standard 1/4 and 1/8 cup measures without error.

One-third cup is common in yogurt parfait recipes, small-batch granola bars, and single-layer cake recipes scaled for 2 servings. It is exactly 80ml in metric volume.
