How would you measure something like 2.5 ounces of butter using a standard US butter stick (which is typically marked in tablespoons and has weight markings), and clarify whether this “ounce” measure is weight-based?

Question

Need 2.5 ounces of butter? Learn how to measure it using a standard stick and find out if the 'ounce' marking refers to weight or volume.

Answer 1

To measure 2.5 ounces of butter, use the tablespoon markings on the butter stick. Since 1 stick (1/2 cup) of butter is 4 ounces or 8 tablespoons, 2.5 ounces is equivalent to 5 tablespoons. The 'ounce' measure on a butter stick refers to weight.

Detailed Explanation:

Here's a breakdown of how to accurately measure 2.5 ounces of butter using a standard US butter stick:

1. Understand the Markings: A standard US butter stick is typically 1/2 cup, which equals 4 ounces (by weight) or 8 tablespoons.

2. Calculate the Equivalent: To find out how many tablespoons equal 2.5 ounces, set up a proportion. If 8 tablespoons = 4 ounces, then x tablespoons = 2.5 ounces. Solving for x: x = (2.5 ounces * 8 tablespoons) / 4 ounces = 5 tablespoons.

3. Cut the Butter: Use a sharp knife to carefully cut off 5 tablespoons of butter from the stick, using the markings as a guide.

4. Confirm the Measurement: While the markings are generally accurate, for critical recipes, you can use a kitchen scale to verify that the cut portion weighs approximately 2.5 ounces.

5. Ounces are Weight-Based: The ounce measurement on a butter stick refers to weight, not volume. Therefore, 4 ounces of butter will weigh 4 ounces.

Pro Tip:

For easier and more accurate cutting, chill the butter slightly before measuring. Soft butter can be difficult to cut cleanly, leading to inaccurate measurements.
