How Much Is 18 Teaspoons of Walnuts in Grams?
18 teaspoons of walnuts weighs 45.00 g. This is based on walnuts having a density of 120g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 18 teaspoons.
Formula and Step-by-Step
- Start with 18 teaspoons of walnuts
- 1 teaspoon of walnuts = 2.5g
- 18 × 2.5 = 45g

Measuring Tip
When a recipe says "1 cup nuts, chopped" vs "1 cup chopped nuts," the first means measure whole then chop. The second means chop first then measure. The weight difference can be significant.

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 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.
