Tag: Teaspoon size

According to the National Institute of Standards and Technology (NIST), a United States customary teaspoon is precisely 4.92892159375 milliliters, which is why 1 tsp is commonly equated to 5ml for practical purposes. This rounding makes it easy for everyday use, but the small difference can be important in certain applications, such as pharmaceutical dosing or chemistry experiments. Understanding this nuance is key to achieving accuracy in your kitchen and for health-related measurements.

One common kitchen misconception is that a teaspoon's volume always translates to a fixed weight, like 10 grams, but this is false. The critical difference between a volume measurement (teaspoon) and a mass measurement (gram) means the weight of one teaspoon varies drastically depending on the ingredient's density.
