How Much Is 138 Grams of Black Beans in Teaspoons?
138 grams of black beans equals 36.00 tsp. Black beans has a density of 184g per cup. Because grams measure weight and teaspoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 138 grams of black beans
- 1 cup of black beans = 184g
- 138g ÷ 184g/cup = 0.75 cups × 48 = 36.00 teaspoons
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 Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Teaspoon?
In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.
