How to measure vegetable oil
The value comes from USDA FoodData Central and matches a density of about 0.92 grams per milliliter. Canola, sunflower, corn and olive oil all land within a few grams of it. Some baking charts list a lower number for a cup of oil, so when a recipe gives grams, use the recipe’s figure. The cleanest way to measure oil is to set the bowl on a scale and pour.
Source: 218 grams per US cup is the cup weight in USDA FoodData Central. A US cup is about 237 milliliters.
