Oil to Butter Converter
Convert between oil and butter amounts for baking and cooking substitutions.
The Oil to Butter Converter helps you substitute oil for butter (or vice versa) in recipes. Butter is about 80% fat and 20% water/milk solids, while oil is 100% fat, so you need more butter than oil.
Enter the amount of oil in grams, and the calculator converts to the equivalent butter amount. The standard conversion factor is 1.2x (multiply oil by 1.2 to get butter). To convert butter to oil, divide butter grams by 1.2.
This substitution works well in most baking recipes, though the texture may differ slightly. Oil-based baked goods tend to be more moist, while butter provides richer flavor and flakier texture.
Frequently Asked Questions
Why is the ratio 1.2 for oil to butter?
Butter is about 80% fat, while oil is 100% fat. So you need 20% more butter to match the fat content of oil: 100/80 = 1.25, rounded to 1.2.
Can I always substitute oil for butter?
For most baking recipes, yes. However, recipes that rely on cold butter (pie crust, croissants) will not work with oil substitution.
Which is healthier, oil or butter?
It depends on the oil. Olive oil and avocado oil have more unsaturated fats. Butter has saturated fat but also vitamins A, D, and E.
