Oil is pure fat
One cup of vegetable oil weighs about 218 g, and nearly all of that weight is fat.

Conversor de aceite a mantequilla
La referencia culinaria exacta para sustituir aceite por mantequilla sin alterar la textura ni el sabor de tus recetas.
Para sustituir aceite por mantequilla, multiplica el aceite por 1.25: 1 cup de aceite se convierte en unas 1¼ cups de mantequilla. En sentido contrario, multiplica la mantequilla por 0.75. Son las reglas generales y sirven para la mayoría de horneados. Si quieres el número que de verdad equilibra la grasa, usa el modo Exacto: la mantequilla solo tiene un 80% de grasa, así que 1 cup de aceite (218 g) necesita 272 g de mantequilla, no las 1⅓ cups que se citan en otros sitios.

- Butter is about 80% fat, so you need more of it by weight to carry the same fat as oil.
- About 80% fat, 16-17% water and milk solids. The water is why butter and oil are not a straight swap.

Why the answer is not always obvious
Cómo funciona la conversión
Dos números lo explican todo: la mantequilla tiene un 80% de grasa y el aceite un 100%. El resto es aritmética.
Butter is about 80% fat
Butter also carries water and milk solids, so matching the fat needs more butter by weight.

The conversion ratio explained
Oil to Butter Ratio
To convert oil to butter quickly, multiply the oil volume by 1.25. That means 1 cup oil becomes 1 1/4 cups butter, 1/2 cup becomes 5/8 cup and 1/4 cup becomes 5 tablespoons.
Quick volume ratio 1.25× Best for everyday measuring
vs
Exact weight formula Oil grams ÷ 0.80 Matches oil fat to 80% fat butter
For baking, the oil to butter replacement ratio works by fat content: oil is essentially 100% fat, while standard butter is about 80% fat. Multiply oil by 1.25 for a practical oil-to-butter swap. For example, 218 g of vegetable oil needs 272.5 g of butter to supply the same fat. The often-repeated 1.333× oil-to-butter substitute ratio comes from reversing the rough butter-to-oil 0.75 rule and is not a true fat match.
Recipe-specific advice
Según el tipo de receta
La proporción no cambia. Lo que cambia es si conviene sustituir, y eso depende de lo que prepares.
Cakes & Cake Mix
For oil to butter in cake or cake mix, use melted, cooled butter so the mixing method remains similar. Expect a richer, slightly firmer crumb. For 1/2 cup oil, the quick oil-to-butter substitute is 5/8 cup butter; mix only until the dry streaks disappear.
Brownies
Butter adds dairy flavour and can make the edges firmer. Melt it, cool it slightly and stir it in where the oil would go; avoid extra beating if you want a dense, fudgy result.
Cookies
This is not always a direct swap. Butter contains water and firms when cool, so cookies may spread, brown and set differently. Use softened butter only when the method calls for creaming.
Banana bread
Melted butter works well and adds richness, while the banana helps retain moisture. Fold it in after cooling and stop mixing as soon as the flour is incorporated.
Muffins
Use melted, cooled butter and combine it with the wet ingredients. The muffins will usually be richer but a little less soft after refrigeration because butter solidifies when cold.
Choose by flavour and structure
Según el tipo de aceite
El aceite vegetal, el de oliva y el de coco no se comportan igual. El de coco es un caso especial.
Vegetable oil to butter
1 cup oil → 1 1/4 cups butterThe most neutral substitution. Butter adds flavour and structure, but the bake may feel less moist once cool.
See the full guideCoconut oil to butter
1 cup coconut oil → 1 cup butterUse a 1:1 volume swap because both fats are solid at typical room temperature. Unrefined coconut oil contributes coconut flavour; refined oil is milder.
See the full guideOlive oil to butter
1 cup oil → about 1 1/4 cups butterButter softens olive oil's grassy or peppery character and adds dairy richness. Mild olive oil suits most bakes; robust extra virgin oil remains noticeable.

Aceite frente a mantequilla
Cambiar la grasa cambia más que la grasa. Esto es lo que se altera de verdad.
| Measure | Vegetable oil | Butter |
|---|---|---|
| Calories per tablespoon | About 120 | About 102 |
| Total fat per tablespoon | About 14 g | About 11.5 g |
| Saturated fat | Varies; usually lower than butter | About 7 g per tablespoon |
| Texture in baking | Moist, soft and tender, even when cool | Firmer crumb with more structure |
| Flavour | Neutral unless the oil is distinctive | Rich dairy flavour and browned notes |
| Best performance | Quick breads, moist cakes and muffins | Cookies, pastry, laminated dough and creamed cakes |
Which has more fat? By tablespoon, oil has more total fat because it is 100% fat; butter includes water and milk solids. Which is healthier? Oils rich in unsaturated fats, such as olive or canola oil, are generally lower in saturated fat than butter. Coconut oil is an exception because it is high in saturated fat. Nutrition values are approximate and vary by brand.

Preguntas frecuentes
¿Cuánta mantequilla equivale a 1 cup de aceite?
Con la regla rápida, 1¼ cups. Ajustado a la grasa son 272 g: 1 cup de aceite pesa 218 g y es 100% grasa, y como la mantequilla solo tiene un 80% de grasa necesitas 218 ÷ 0.80 = 272 g.
¿Cuál es la proporción de aceite a mantequilla?
De aceite a mantequilla es 1.25, y de mantequilla a aceite 0.75. Es decir, usa una cuarta parte más de mantequilla que el aceite indicado.
¿Por qué algunas webs dicen 1.33 en lugar de 1.25?
Porque 1 ÷ 0.75 = 1.333. Alguien invirtió la regla en vez de partir del contenido de grasa. La mantequilla tiene un 80% de grasa, no un 75%, así que el multiplicador correcto es 1.25.
¿Puedo sustituir aceite por mantequilla en repostería?
Normalmente sí, y funciona mejor cuando la grasa se añade fundida o líquida: brownies, bizcochos y magdalenas. Funciona peor cuando la mantequilla se bate con azúcar para incorporar aire.
¿Cuánto aceite sustituye a 100 g de mantequilla?
80 g de aceite, unos 87 ml. La mantequilla es 80% grasa, así que 100 g aportan 80 g de grasa, y el aceite es grasa pura.
¿Y el aceite de coco?
Es la excepción real. El aceite de coco es sólido por debajo de unos 24°C, se comporta como la mantequilla y se sustituye 1:1 por volumen.
¿Hay que ajustar el líquido al sustituir?
Si cambias mantequilla por aceite, sí. La mantequilla tiene un 16% de agua, así que conviene añadir una cucharada de leche o agua por cada 100 g de mantequilla sustituida.
¿Es más sano el aceite o la mantequilla?
Por cucharada las calorías son parecidas, unas 120 el aceite y 100 la mantequilla, que contiene agua. La diferencia real es el tipo de grasa: la mantequilla es un 63% saturada.
