Convert Cups to Grams: Vegetable Oil
Convert cups of vegetable oil to grams with this complete reference table. 1 cup of vegetable oil = 218g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because vegetable oil density can vary by measuring technique.

| Cups | Grams |
|---|---|
| 1/8 cup | 27.3g |
| 1/4 cup | 54.5g |
| 1/3 cup | 72.7g |
| 1/2 cup | 109g |
| 2/3 cup | 145.3g |
| 3/4 cup | 163.5g |
| 1 cup | 218g |
| 1 1/4 cups | 272.5g |
| 1 1/2 cups | 327g |
| 2 cups | 436g |
| 3 cups | 654g |
| 4 cups | 872g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Vegetable oil (canola, soybean blend) is lighter than water — all fats are. 1 cup = 218g. Oil is always liquid at room temperature. For baking, oils add moisture differently than butter (no steam = denser crumb).
About Vegetable Oil Density
The density of vegetable oil determines how much it weighs per unit of volume. At 0.908g/ml, 1 US cup (240ml) of vegetable oil weighs 218g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
Frequently Asked Questions
How many grams is 1 cup of vegetable oil?
1 cup of vegetable oil weighs 218 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
How many grams is 1/2 cup of vegetable oil?
1/2 cup of vegetable oil weighs 109 grams.
How many grams is 1/4 cup of vegetable oil?
1/4 cup of vegetable oil weighs 55 grams.
Does measuring technique affect the weight of vegetable oil?
Yes. Sifted vegetable oil can weigh up to 20% less than packed or scooped. The USDA standard (spooned-and-leveled) of 218g/cup is the most reliable baseline.
