Formula and Step-by-Step
- Start with 109 teaspoons of black beans
- 1 teaspoon of black beans = 3.83g
- 109 × 3.83 = 417.83g

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.
