Oil Grams to Cups Converter
100g of olive oil is about 0.46 US cups, using our reference of 216g per cup.
This page uses olive oil as its default, not a universal weight for every cooking oil. Enter your olive oil weight below to convert another amount.
Reference: The USDA's Nutritive Value of Foods, page 24 lists olive oil at 216g per cup. We adopt that weight for this site's US Customary setting. The publication was revised in 2002; the result is a reference-based estimate, not a new measurement of your bottle.

Can I use this for vegetable oil or another cooking oil?
Check the oil named in your recipe and the reference you are using. Different cooking oils should not automatically share one cup weight, and a product labeled vegetable oil may be a different oil or blend.
For comparison, the same USDA publication lists canola oil at 218g per cup, while its olive oil entry is 216g. Those references are close, but they are not identical. The calculator on this page uses the olive oil figure.
If your recipe or product provides its own cup-and-gram equivalent, follow that. Do not assume this converter has identified your oil from its bottle or label.
How to measure olive oil
If your recipe gives grams and you have a kitchen scale:
- Place an empty bowl on the scale and press tare or zero.
- Pour in the olive oil slowly.
- Stop at the requested weight, allowing the display to settle as you approach it.
You can weigh into a separate bowl before adding the oil to other ingredients, making an accidental excess easier to remove.
For a cup measurement, use a marked liquid measuring cup on a level surface and read the amount at eye level. Betty Crocker's measuring guide recommends that approach for liquid ingredients. Let the oil drain into the mixing bowl so you do not leave a noticeable portion in the measure.
How to convert oil grams to cups
For this page's olive oil reference:
Cups = grams ÷ 216
For example, 250 ÷ 216 = about 1.16 US cups. Keep the full calculation until the final display rather than rounding the reference first.
For the reverse calculation, multiply cups by 216. That gives 108g for ½ cup and 54g for ¼ cup. Switch direction in the calculator, or use the cups-to-grams converter with olive oil selected.
Are grams and milliliters interchangeable for oil?
No. Grams measure weight; milliliters measure volume. This page's reference assigns 216g of olive oil to the site's 236.588mL US Customary cup, so the gram and milliliter numbers are not the same.
If a recipe already gives milliliters, use those volume markings on your measuring jug. If it gives grams, weigh the oil or use an ingredient-specific conversion. Do not read 100g as 100mL just because both are metric units.
What changes with a metric cup?
Choose Metric in the calculator for a 250mL cup. Scaling the olive oil baseline by cup volume gives about 228.2g per metric cup. That is a calculated estimate, not a separate USDA metric-cup measurement.
The chart above remains fixed to US Customary. Read the cup-size guide for the supported settings and the methodology for calculation and rounding details. The grams-per-cup chart lists the references used for other ingredients.
