How to measure it
Vegetable oil weighs about 218 g a cup, roughly 8 percent lighter than the same cup of water. That is why oil floats, and why using the water figure of 236 g for oil quietly adds an extra tablespoon and a half to every cup.
Canola, sunflower, corn and light olive oil all sit within a couple of grams of the same density, so one figure covers the neutral oils. Extra virgin olive oil is essentially identical by weight; choose it for flavour, not conversion reasons.
Oil pours cleanly and completely, so unlike honey there is no sticking loss. A liquid measuring cup at eye level is accurate enough for any recipe.
Density source: Government food composition data. Method assumed: Neutral vegetable oil at room temperature.
