How Much Is 1.5 Teaspoons of Butter in Ounces?
Converting 1.5 teaspoons of butter to ounces gives 0.25 oz. One teaspoon of butter weighs 4.73g, so 1.5 teaspoons is 1.5 × 4.73 = 7.09g (0.25 oz). This conversion is specific to butter because each ingredient has a different density.
Formula and Step-by-Step
- Start with 1.5 teaspoons of butter
- 1 teaspoon of butter = 4.73g
- 1.5 × 4.73 = 7.09g
- Convert grams to ounces: 7.09 ÷ 28.3495 = 0.25 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Butter is easiest to measure using the markings on the wrapper. One US stick = 113g = 1/2 cup = 8 tablespoons.

Understanding the Units
What is a Teaspoon?
A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
