How Much Is 150 Teaspoons of Black Pepper in Ounces?
150 teaspoons of black pepper weighs 12.79 oz. This is based on black pepper having a density of 116g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 150 teaspoons.
Formula and Step-by-Step
- Start with 150 teaspoons of black pepper
- 1 teaspoon of black pepper = 2.42g
- 150 × 2.42 = 362.5g
- Convert grams to ounces: 362.5 ÷ 28.3495 = 12.79 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Ground spices like black pepper settle and compact during storage. Stir or fluff before measuring by volume for a consistent amount.

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.
