Butter Conversion Calculator

About the Butter Conversion Calculator

Butter is measured differently depending on where you live and what recipe you're following. American recipes call for sticks and cups, European recipes use grams, and some older cookbooks list ounces or tablespoons. Getting the conversion wrong by even a tablespoon can throw off cookies, cakes, and pastries. This Butter Conversion Calculator handles every common butter measurement.

One US stick of butter equals exactly 113 grams, 4 ounces, 8 tablespoons, or ½ cup. These are the anchor conversions from which everything else derives. But butter also varies by fat content — American butter is 80% fat minimum, while European-style butter (like Plugra or Kerrygold) is 82–86% fat. That extra fat content means European butter has less water, which affects baking outcomes.

This calculator converts between all common units quickly. Enter any amount in any unit and see the equivalent in sticks, cups, tablespoons, grams, ounces, and pounds. It also shows calorie counts and distinguishes between cold (solid) and melted butter volumes, since melted butter is denser and occupies less volume.

When This Page Helps

Use this calculator when a recipe moves between sticks, cups, tablespoons, grams, or ounces. It keeps butter conversions anchored to the standard US stick so you can scale recipes accurately and account for melted or solid butter measurements.

How to Use the Inputs

1. Select the unit you're converting from (sticks, grams, cups, etc.)
2. Enter the amount of butter
3. View direct conversions to all other units
4. Check the calorie and fat content for your amount
5. Use the reference table for quick lookups
6. Note the melted vs solid volume difference

Example Calculation

Tips & Best Practices

• US butter sticks have tablespoon markings on the wrapper — use them for easy measuring
• For precise baking, weigh butter in grams rather than measuring by volume
• Softened butter (room temp) and cold butter have different volumes — always measure cold then soften
• European-style butter produces flakier croissants and more tender cakes
• Freeze butter for up to 6 months — it thaws quickly at room temperature
• Clarified butter (ghee) has had water removed — 1 cup butter = about ¾ cup ghee

US vs European Butter Standards

American butter must contain at least 80% milk fat by USDA regulation. Most mass-market brands (Land O'Lakes, store brands) sit right at 80%. European-style butter ranges from 82% to 86% fat. Brands like Kerrygold, Plugra, and President are European-style. The extra 2–6% fat means less water content, which creates flakier pastry layers and smoother buttercream.

Measuring Butter Accurately

The most accurate way to measure butter is by weight. Volume measurements (cups, tablespoons) can vary depending on how tightly butter is packed. For serious baking, use a kitchen scale. A stick of butter is always exactly 113g regardless of how you cut or pack it.

Butter Substitutes and Ratios

Margarine substitutes 1:1 for butter in most recipes but has different flavor and browning characteristics. Coconut oil can replace butter at a 1:1 ratio but adds coconut flavor. For dairy-free baking, vegan butter sticks (Miyoko's, Earth Balance) work cup-for-cup in most recipes.

Frequently Asked Questions

• How many grams in a stick of butter?

  113 grams (4 ounces). A US stick is ½ cup or 8 tablespoons.

• How many tablespoons in a stick of butter?

  8 tablespoons. US butter sticks are conveniently marked with tablespoon lines on the wrapper.

• What's the difference between US and European butter?

  US butter is minimum 80% fat. European butter is 82–86% fat with less water. European butter makes flakier pastries and richer sauces.

• Does melted butter measure differently?

  Yes — melted butter is slightly denser. 1 cup solid butter ≈ 7/8 cup when melted. Always measure butter in its solid form unless the recipe specifies melted.

• Can I substitute oil for butter?

  For baking, use 7/8 the volume of oil (butter contains water). For sautéing, substitute 1:1. Flavor and texture will differ.

• How many calories in a tablespoon of butter?

  About 102 calories and 11.5g fat per tablespoon (14.2g) of butter.
