Butter: Cups to Grams

Estimate a butter cup portion in grams or ounces by weight. If your package or recipe already gives a weight, use it directly.

Read the original portion

The record comes from the butter entry in King Arthur Baking’s ingredient weight chart. The calculator preserves its half-cup source portion and scales from the chart’s gram figure.

The source’s cup capacity is not confirmed in milliliters, so this is a source-portion estimate. It is not a measured density for switching between different cup standards.

Why a package may show a different number

A chart’s gram and ounce columns can be rounded separately. Here, the ingredient calculation uses the recorded gram amount; any ounces by weight are converted from it. That keeps the displayed result internally consistent without treating a rounded kitchen chart as an exact physical definition.

If you know the package weight in ounces, use ounces to grams for a direct weight conversion. You do not need a butter portion record for that task.

Follow the recipe’s preparation wording

Keep instructions such as softened, melted, or measured before melting with the quantity. This chart record does not establish separate densities for every preparation. It also does not establish a universal size for an item described as a “stick.” Check the package instead.

For another food, use the ingredient directory. For the unit distinction, read fluid ounces versus ounces by weight.
