Measuring Vegetable Oil Accurately
Why weight matters: 2/3 cup of vegetable oil can weigh anywhere from 124g to 174g depending on how you measure it. The USDA standard is 145.33g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About vegetable oil density: Vegetable oil (canola, soybean blend) is lighter than water — all fats are. 1 cup = 218g. Oil is always liquid at room temperature. For baking, oils add moisture differently than butter (no steam = denser crumb).
About 2/3 Cup as a Measurement
2/3 cup = 10 tablespoons + 2 teaspoons = 160ml. This measure appears when scaling up 1/3 cup recipes by doubling. Use two 1/3-cup measures for accuracy, as 2/3 cup sets are less common.
Two-thirds cup is often seen in oatmeal cookie recipes, breakfast grain bowls, and rice cooker recipes for 2 servings. It equals exactly 160ml or approximately 5.4 fluid ounces.
