About vegetable oil measurements
Vegetable oil measures about 0.92 g/ml (FAO density database), roughly 218 g per US cup — well under water, since fats are lighter. Blended, refined oils hold that number closely, while unrefined or cold-pressed oils carrying suspended solids can read a little heavier per cup.
