What is the fat content of both butter and margarine?

Butter and margarine are both known for having similar fat content, which typically ranges around 80%. This is a standard figure for both products in their regular forms. The fat in these products is an essential component that contributes to their texture, flavor, and cooking properties.

Margarine can vary slightly in fat content depending on the type and brand, but most commonly available margarine sticks are formulated to match the fat content of butter to allow for equivalent usage in recipes. Therefore, the choice indicating 80% accurately reflects the typical fat content found in standard butter and margarine, making it the correct answer for this question.
