Enter your butter amount and choose your unit (teaspoons, tablespoons, or cups) to get the exact oil equivalent for your recipe. Select your preferred oil type — olive, vegetable, coconut, or canola — and the Butter to Oil Conversion tool returns the precise substitution amount plus a handy breakdown of the swap.

The standard ratio is 3/4 the amount of oil for every unit of butter. For example, 1 cup of butter equals 3/4 cup of oil, and 1 tablespoon of butter equals 2.25 teaspoons of oil. This applies to most liquid oils like olive, vegetable, and canola oil.
One stick of butter is 1/2 cup (8 tablespoons). Using the 3/4 ratio, that equals 6 tablespoons (or 1/4 cup + 2 tablespoons) of oil. This conversion works for olive oil, vegetable oil, canola oil, and most other liquid cooking oils.
For a neutral flavor, vegetable oil or canola oil are the best choices since they won't alter the taste of your baked goods. Light or pure olive oil also works well with a very mild flavor. Extra virgin olive oil adds a fruity, slightly robust taste that can complement certain recipes like brownies or savory muffins.
Yes, you can substitute oil for butter in most cookie recipes. Use 3/4 the amount of oil compared to butter. Keep in mind that butter adds structure and a slightly crispy edge, so cookies made with oil may spread a bit more and have a softer, chewier texture. The flavor will also be slightly different.
Oil-based cakes tend to be moister and stay fresh longer than butter-based cakes because oil is a liquid fat that coats flour proteins more evenly. Butter, on the other hand, contributes to a richer flavor and can produce a slightly denser, more structured crumb. For very moist cakes like carrot cake or banana bread, oil is often preferred.
Oil cannot replace butter in recipes where butter's solid fat is essential for structure or texture — such as pie crusts, croissants, puff pastry, shortbread, and frosting. These recipes rely on butter's ability to create layers or hold a specific form that liquid oils cannot replicate.
Yes, replacing butter with most plant-based oils significantly reduces saturated fat. Butter contains around 7g of saturated fat per tablespoon, while olive oil contains about 2g and vegetable oil around 1.5g per tablespoon. This swap can make baked goods a more heart-healthy choice.
Yes, it is safe to cook with extra virgin olive oil. Its smoke point is around 375–405°F (190–207°C), which is suitable for most baking, sautéing, and moderate-heat cooking. For very high-heat cooking like deep frying, a refined oil with a higher smoke point may be more appropriate.
