How Much Is 135 Teaspoons of Black Beans in Ounces?
135 teaspoons of black beans weighs 18.25 oz. This is based on black beans having a density of 184g 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 135 teaspoons.
Formula and Step-by-Step
- Start with 135 teaspoons of black beans
- 1 teaspoon of black beans = 3.83g
- 135 × 3.83 = 517.5g
- Convert grams to ounces: 517.5 ÷ 28.3495 = 18.25 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
These conversions are for dry, uncooked black beans. Cooked legumes absorb water and have a completely different weight per cup.

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.
