Butter Converter

How it is calculated

Whatever unit you choose is first converted to grams using fixed US factors: 1 tbsp = 14.1748 g, 1 stick = 113.398 g, 1 cup = 226.796 g. The gram value is then divided by each factor to give tablespoons, sticks and cups, so the formula is result = (amount × factor of input unit) ÷ factor of target unit. One stick equals 8 tablespoons or half a cup. Results use two decimals. The factors describe US butter measures; other countries' tablespoons or cups differ slightly, and negative amounts are rejected. This is weight-based conversion, so it is not valid for melted or whipped butter measured by volume.

Common mistakes

• Treating a stick as a cup: one US stick is only half a cup, or 8 tablespoons.
• Using European 250 g butter blocks as if they were 2 sticks; 2 sticks are about 227 g, so a small gap remains.
• Measuring softened or melted butter by volume in a cup, which packs differently than cold butter.
• Mixing up US tablespoons with other countries' tablespoons, which are a different size.
