Olive oil weighs 216 grams per cup, slightly lighter than vegetable oil's 218g — both are neutral-density fats close enough that this site's figure works across olive oil grades, though extra virgin, virgin, and refined ("light" or "pure") olive oil differ meaningfully in flavor, smoke point, and price despite sharing essentially the same weight per cup.
Extra virgin olive oil is the least processed grade — cold-pressed from olives with no chemical refining — which gives it the most pronounced olive flavor and the lowest smoke point among the olive oil grades, while refined olive oil (sometimes labeled "light" or "pure," a reference to flavor and color, not calories) has been processed to be more neutral-tasting and heat-tolerant.
Extra virgin olive oil's minimal processing also means it retains more of the natural compounds that eventually go rancid, giving it a shorter practical shelf life once opened than a more refined oil — worth knowing since olive oil's reputation as a "healthy" pantry staple doesn't mean it's exempt from the same rancidity concerns any other oil faces.
Olive oil's 216g-per-cup weight makes it the lightest common cooking oil on this site, marginally below vegetable oil's 218g — extra-virgin olive oil, pressed without heat or chemical extraction, retains more of the olive's natural flavor compounds than refined olive oil, a distinction that affects taste and smoke point far more than it affects this conversion figure.
Extra-virgin olive oil has a lower smoke point than refined olive oil or a neutral vegetable oil, which is why many cooks reserve it for finishing a dish or lower-heat cooking, saving a more refined, higher-smoke-point oil for high-heat searing or frying.

Frequently asked questions
Does the olive oil grade (extra virgin vs. regular) change this conversion?
Not meaningfully — extra virgin, virgin, and refined olive oil all sit close enough in density to share this site's 216g/cup figure; the real differences between grades are flavor intensity, smoke point, and processing, not weight.
Why does extra virgin olive oil cost more and taste stronger than "light" olive oil?
Extra virgin is cold-pressed with no chemical refining, preserving more of the olive's natural flavor compounds, while "light" or refined olive oil has been processed to be more neutral in taste and color — that extra processing is also what raises its smoke point.
Is olive oil a good substitute for vegetable oil in baking?
It works in savory baking (like olive oil cake or focaccia) where its flavor is welcome, but its distinct taste can clash in a delicately flavored sweet recipe where vegetable oil's neutrality is actually the point.
Why does olive oil go rancid faster once opened than vegetable oil?
Extra virgin olive oil in particular retains more natural compounds due to its minimal processing, and those same compounds that give it flavor also oxidize and turn rancid faster once exposed to air, light, and heat than a more heavily refined oil.
Should olive oil be refrigerated to extend its shelf life?
It's not this site's recommended approach — like other oils, refrigeration offers little rancidity benefit and can cause olive oil to turn cloudy or partially solidify; a cool, dark cabinet away from the stove is the better storage choice.
