Butter Calculator
Our cooking calculator handles butter conversions. Scale recipes, convert units, and adjust servings accurately. Enter your values for instant results.
Formula
Weight (g) = Amount × Unit Conversion Factor
Butter conversions are based on standard density (0.911 g/mL) and US measurements: 1 stick = 113.5g = 1/2 cup = 8 tbsp. Nutritional values are calculated from USDA data per gram of butter.
Worked Examples
Example 1: Converting a European Recipe
Problem: A French pastry recipe calls for 250 grams of butter. Convert to US sticks and cups.
Solution: 250g ÷ 113.5g per stick = 2.20 sticks\n250g ÷ 227g per cup = 1.10 cups\n250g ÷ 14.1875g per tbsp = 17.6 tablespoons\nNearest practical measure: 2 sticks + 2.5 tablespoons
Result: 250g = 2.20 sticks = 1.10 cups = 17.6 tbsp
Example 2: Butter Nutrition for a Recipe
Problem: A cookie recipe uses 2 sticks of butter. What is the total fat and calorie content from the butter alone?
Solution: 2 sticks = 227g of butter\nCalories: 227 × 7.17 = 1,628 calories\nTotal Fat: 227 × 0.811 = 184.1g\nSaturated Fat: 227 × 0.511 = 116.1g\nIf recipe makes 36 cookies: ~45 cal and ~5.1g fat per cookie from butter
Result: 2 sticks = 1,628 cal | 184.1g fat | 116.1g saturated fat
Frequently Asked Questions
How many grams are in a stick of butter?
A standard US stick of butter weighs 113.5 grams (4 ounces or 1/2 cup). US butter is typically sold in packages of four sticks, totaling one pound (454 grams). Each stick is conveniently marked with tablespoon measurements on the wrapper: one stick equals 8 tablespoons. In many recipes, especially those from the United States, butter is measured in sticks for convenience. European butter is usually sold in blocks of 250 grams or 500 grams and is not divided into sticks. When converting between US and metric recipes, knowing that one stick equals 113.5 grams is essential. Half a stick is approximately 57 grams or 4 tablespoons, which is a common quantity in baking recipes for cookies and cakes.
How do I convert cups of butter to grams?
One cup of butter equals approximately 227 grams (8 ounces or 2 standard US sticks). This conversion is based on butter's density of approximately 0.911 grams per milliliter, which is slightly less than water. To convert any cup measurement to grams, multiply the number of cups by 227. Common conversions include: 1/4 cup = 57g (half a stick), 1/3 cup = 76g, 1/2 cup = 113.5g (one stick), 2/3 cup = 151g, 3/4 cup = 170g, and 1 cup = 227g. Weight measurements (grams) are more accurate than volume measurements (cups) for baking because they are not affected by how tightly the butter is packed or whether it has been softened. Professional bakers almost always use weight measurements for consistent results.
Can I substitute oil for butter in baking?
Yes, you can substitute oil for butter in many baking recipes, but the ratio is not one-to-one because butter contains about 80% fat plus water and milk solids, while oil is 100% fat. The general rule is to use 3/4 the amount of oil compared to butter. For example, if a recipe calls for 1 cup (227g) of butter, use 3/4 cup (180 mL) of oil. However, this substitution changes the texture significantly. Butter creates flaky layers in pastries and crisp edges in cookies due to its solid-to-liquid transition during baking. Oil produces moister, denser results. For cakes and muffins, oil works well and often produces a moister crumb. For cookies and pastries where texture is critical, butter is generally preferred. Coconut oil can be used as a closer substitute since it is also solid at room temperature.
What is the nutritional content of butter?
One tablespoon (14.2 grams) of salted butter contains approximately 102 calories, 11.5 grams of total fat, 7.3 grams of saturated fat, 30.5 mg of cholesterol, 91 mg of sodium, and virtually no carbohydrates or protein. Butter is a significant source of vitamin A (97 IU per tablespoon) and also contains small amounts of vitamins D, E, and K2. The high saturated fat content has been controversial in nutrition science. While older guidelines strictly limited butter intake, more recent research suggests that the relationship between saturated fat and heart disease is more nuanced than previously thought. Grass-fed butter contains higher levels of omega-3 fatty acids and conjugated linoleic acid (CLA). Unsalted butter has the same calorie and fat content but significantly less sodium, typically less than 10 mg per tablespoon.
What is the difference between salted and unsalted butter?
Salted and unsalted butter differ primarily in their sodium content and shelf life. Salted butter contains approximately 90 mg of sodium per tablespoon, while unsalted butter has less than 10 mg. The salt in salted butter acts as a preservative, giving it a longer refrigerated shelf life of about 5 months compared to 3 months for unsalted. In cooking, professional bakers strongly prefer unsalted butter because it allows precise control over the salt content of the final product. Salt levels vary between brands, making results inconsistent if salted butter is used. When a recipe calls for unsalted butter, you can substitute salted butter by reducing the added salt by about 1/4 teaspoon per stick (113.5g) of butter used. For cooking savory dishes, either type works well. The fat content, calorie count, and baking properties are identical between the two types.
