2 Cups Vegetable Oil in Grams
If you need 2 cups of vegetable oil in grams, the answer is 436 g — measured poured, according to USDA. You are probably here mid-recipe, so here is the number first and the explanation second. The rest of this page gives you the full conversion table for vegetable oil, worked examples from real recipes, the measuring method behind the number, and the mistakes that most often throw this conversion off. All weights here are approximate; a kitchen scale is the final word when precision counts.
The problem with cups, in one paragraph
A cup looks like a fixed unit, but for vegetable oil it is not. The same cup can hold more or less depending on how the ingredient settled in its container, whether it was spooned in or scooped, and whether it was levelled or heaped. With 2 cups of vegetable oil, the gap between a careful spoon-and-level measure and a careless scoop can be tens of grams — enough to change a recipe. Weighing 436 g instead removes the whole question. It is also faster once you get used to it: put the bowl on the scale, press tare, and pour until the display reads 436. No levelling, no sweeping, no second-guessing. The table below gives you every amount you are likely to need, so you can weigh instead of measuring by volume from now on.
Vegetable Oil cups to grams conversion table
| Cups | Grams | Tablespoons (approx.) |
|---|---|---|
| 1/4 cup | 54.5 g | 3.4 g |
| 1/3 cup | 72.7 g | 4.5 g |
| 1/2 cup | 109 g | 6.8 g |
| 2/3 cup | 145.3 g | 9.1 g |
| 3/4 cup | 163.5 g | 10.2 g |
| 1 cup | 218 g | 13.6 g |
| 1 1/2 cups | 327 g | 20.4 g |
| 2 cups | 436 g | 27.2 g |
| 3 cups | 654 g | 40.9 g |
| 4 cups | 872 g | 54.5 g |
The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of vegetable oil weighs about 13.6 g. Remember that a cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded sensibly. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one.
How the weight was measured
Poured means the ingredient was measured the way USDA measures it: poured into a liquid measuring jug and read at eye level at the meniscus. Liquids do not pack, so the main source of error is reading the jug from above or using a dry cup for a liquid measure. The source for the 218 g per cup figure is USDA, and the confidence in the value is high. USDA publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
There is a dispute worth knowing about. USDA density (0.92 g/ml) gives 218 g per cup. The King Arthur chart lists 198 g for vegetable oil, which appears to be an error carried from a smaller measure; we use the USDA density value. The practical advice is simple: use the value in the table above, measure the way the table describes, and your results will match the recipes this site is built around. If a recipe you are following was written with a different value, follow that recipe's value instead of ours, because consistency within one recipe matters more than which authoritative number you pick.
Worked examples
Roasting vegetables for a dinner party
Roasting a large tray of vegetables with 2 cups of vegetable oil needs 436 g drizzled over the top. Weighing the oil stops you from drowning the vegetables (soggy) or starving them (dry and burnt at the edges). Toss, spread in a single layer, and roast hot.
A cake that swaps butter for oil
Some cakes use oil instead of butter for a moist crumb. If the recipe calls for 2 cups of vegetable oil, weigh 436 g and pour it in. Oil cakes mix fast — no creaming step — so the weighing is the only precision step in the whole recipe, and it is worth doing properly.
Pastry where the fat ratio decides the flake
Flaky pastry is a ratio: the fat must be cold and the amount exact. A recipe calling for 2 cups of vegetable oil needs 436 g. Too much fat and the pastry is greasy and collapses; too little and it is tough. Weigh the fat, cut it in cold, and keep everything chilled — the scale and the fridge do more for your pastry than any technique tip.
When you do not have a scale
If you have no scale, spoon and level is your best method: spoon vegetable oil into the cup until it is heaped, then sweep a straight knife across the rim. Do not scoop, do not tap the cup, and do not shake it down. For 2 cups, fill the cup twice, levelling each time. It will not be as accurate as weighing 436 g, but it will be far closer than scooping. A useful check: a cup of vegetable oil weighed on a friend's scale once tells you what your spoon-and-level cup actually weighs, and you can adjust from there. If you bake more than once a month, a basic digital scale is the single best purchase you can make for your kitchen — it costs little, takes up no space, and removes the biggest source of recipe failure.
Frequently asked questions
How many grams is 2 cups of vegetable oil?
2 cups of vegetable oil weighs approximately 436 g, measured poured. The figure comes from the USDA value of 218 g per cup. All weights on this page are approximate — verify with a kitchen scale when precision matters.
Can I halve or double this amount?
Yes. Half of 2 cups of vegetable oil is 218 g, and double is 872 g. Weighing makes scaling exact, whereas halving or doubling cups compounds measuring error. Scale the vegetable oil by weight and adjust leavening and seasoning by taste rather than by a straight multiple.
How should I store vegetable oil?
Cool, dark cupboard; use within 6 months of opening. Keeping it sealed and dry also keeps the cup weight close to the 218 g per cup value used on this page.
Why do different sources give different weights for vegetable oil?
Because a cup measures volume, not weight, and the weight of a volume depends on the measuring method. Spooned and levelled, scooped, sifted and packed cups of vegetable oil all weigh different amounts. This page follows the USDA method (poured) consistently, so all the numbers here agree with each other — which matters more than matching any single outside source.
Can I use a cup instead of weighing vegetable oil?
Yes, but spoon and level rather than scooping: spoon vegetable oil into the cup until heaped, then sweep a knife across the top. Scooping packs the ingredient and can add 10 to 20 percent extra weight. For 2 cups, fill and level the cup twice. Weighing 436 g is more accurate and, once you are used to it, faster.
