How many grams are in a cup of vegetable oil?
One US cup of vegetable oil weighs about 218 grams (7.7 ounces). Half a cup is about 109 g, and one tablespoon is about 14 g.
Cooking oil is lighter than water, so a cup of oil weighs less than a cup of water even though the volume is the same. Olive, canola and vegetable oil are all within a few grams of each other.

Why a cup of oil weighs less than a cup of water
Oil is lighter than water, which is why it floats. A cup of vegetable oil weighs about 218 g, roughly 8 percent less than the 237 g of a cup of water. One milliliter of oil weighs about 0.92 g, so 100 g of oil is about 109 ml. Canola, olive, sunflower and other liquid cooking oils are within a few grams of each other.
Oil clings to measuring cups, so about a tablespoon can stay behind. For the most accurate result, set the mixing bowl on a scale, tare it, and pour the oil in by weight. Melted coconut oil weighs about the same as vegetable oil, but solid coconut oil should be melted before you measure it.
Oil versus butter in baking
Butter is only about 80 percent fat, with the rest mostly water, so oil does not replace it one for one. The usual rule is to use about ¾ cup of oil for each cup of butter, which is about 164 g of oil in place of 227 g of butter. Cakes made with oil stay moist for days, while butter gives better flavor and a firmer crumb.
Box cake mixes and quick breads commonly use ⅓ to ½ cup of oil, which is 73 to 109 g. For shallow frying, you need enough oil to come halfway up the food, and for deep frying 2 to 3 inches of depth in a heavy pot. Pick an oil with a high smoke point, such as canola or peanut, for high-heat cooking.
