Butter to Oil Converter

Butter is a solid fat that adds flavour and, when creamed, traps air for lift that oil cannot give. To swap oil for butter, use about 1 cup plus 2 tablespoons of butter per cup of oil, and our butter to oil converter handles the exact amount. See our Butter converter.

Ghee is a clarified butter fat, almost the same weight as vegetable oil (218 g vs 220 g per cup) but with a nutty flavour and a higher smoke point. Swap for melted ghee where a neutral fat is not essential. See our Ghee converter.
