Oil to Butter Conversion
Convert baking measurements between butter and cooking oil
Conversion Rule: Butter contains about 80–85% fat and 15–20% water, whereas cooking oil is 100% pure fat. Therefore, when substituting oil for butter (or vice versa), the standard baking ratio is $1:\text{0.8}$ by weight (use 80% oil compared to butter). Enter your butter weight below.
