20g Vegetable Oil to Cups
20 grams of vegetable oil is a small amount, best measured with a spoon rather than a full cup. At 218g per cup, it works out to 1.5 tablespoons.

20 grams of vegetable oil = 0.09 cups (⅛ cup / 1.5 tbsp / 4.4 tsp)
Vegetable Oil has a density of approximately 218g per cup. Canola, corn, and soybean oil sold as 'vegetable oil' vary by only a gram or two. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.
| Grams | Cups | Fraction | Tablespoons | Teaspoons |
|---|---|---|---|---|
| 10g | 0.05 | ⅛ | 0.7 | 2.2 |
| 15g | 0.07 | ⅛ | 1.1 | 3.3 |
| 20g | 0.09 | ⅛ | 1.5 | 4.4 |
| 25g | 0.11 | ⅛ | 1.8 | 5.5 |
| 30g | 0.14 | ⅛ | 2.2 | 6.6 |
The Math for 20g of Vegetable Oil
20g divided by 218g (the weight of one cup of vegetable oil) equals 0.09 cups. Multiplying that by 16 gives 1.5 tablespoons, and by 48 gives 4.4 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.
Vegetable Oil is lighter than water, which weighs about 236g per cup. That's why 20g of vegetable oil takes up more volume (22ml) than the same weight of water would (20ml). For a side-by-side look at how other ingredients compare, see the 20 grams to cups page.
Metric and Imperial Cup Sizes
The 0.09 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 20g, that's ⅛ metric cups or ⅛ imperial cups of vegetable oil, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.
Making More or Less Than 20g
Doubling a recipe that calls for 20g of vegetable oil means weighing 40g, or measuring 0.18 cups if you're working by volume instead of weight. Halving it means 10g, or 0.05 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.
How Vegetable Oil Compares to Similar Ingredients
Within fats & oils, density still varies by ingredient. At 20g, olive oil (216g per cup) measures ⅛ cup, while butter (227g per cup) measures ⅛ cup, compared to ⅛ cup for vegetable oil. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.
Using Vegetable Oil in Recipes
- Recipes typically call for this ingredient in amounts ranging from a tablespoon to a full cup, depending on the dish.
- Check your specific recipe for the exact gram amount, then use the converter above to find the matching cup measurement.
Getting an Accurate Spoon Measurement
Fats & Oils
Press solid fats like butter into the cup to remove air pockets, then level the top. Liquid oils should be poured to the marked line at eye level.
For exact results
Room-temperature butter measures more consistently than cold butter, since cold butter can leave small gaps when pressed into a cup. For melted butter, measure the volume after melting, not before, since melting slightly changes how it fills a cup.

Frequently Asked Questions
What is 20 grams of vegetable oil in cups?+
20 grams of vegetable oil is 0.09 cups, or 1.5 tablespoons.
Should I use a spoon or a cup for 20g of vegetable oil?+
At 20g, a tablespoon or teaspoon measurement is usually more practical than a fractional cup. Use 1.5 tablespoons or 4.4 teaspoons.
Is 20 grams of vegetable oil the same as 20 milliliters?+
Only if it weighed the same as water. 20g of water is about 20ml, while 20g of vegetable oil is 22ml, because the two have different densities.
Does the answer change for a metric or imperial cup?+
Slightly. 20g of vegetable oil is ⅛ metric cups or ⅛ imperial cups, close to the US figure but not identical, since each standard defines the cup at a different volume.
