1 teaspoon of walnuts weighs 2.35 g. A teaspoon is one forty-eighth of a cup, and a cup of walnuts is 113 g spooned and levelled, so the maths is 113 ÷ 48 = 2.35 g. The same cup divided by 16 gives the tablespoon weight of 7.1 g, and there are 3 teaspoons in every tablespoon. If you cook from recipes written in cups and spoons, this page is the bridge between the two, and the worked examples show the conversion inside real dishes rather than in isolation.
Chopped walnut pieces with a rich, slightly bitter flavour. It is used for brownies, salads, pesto and banana bread.
All figures on this page are approximate, and they come from King Arthur Baking, measured spooned and levelled. When a recipe has to work the first time, verify with a kitchen scale.
Conversion table
One teaspoon is one forty-eighth of a cup, so every figure in this table is the cup weight divided by 48, rounded to two decimal places. All figures are approximate; verify with a kitchen scale when it matters.
| Teaspoons | Grams (approx.) |
|---|---|
| 1 tsp | 2.35 g |
| 2 tsp | 4.7 g |
| 3 tsp | 7.05 g |
| 4 tsp | 9.4 g |
| 5 tsp | 11.75 g |
| 6 tsp | 14.1 g |
| 7 tsp | 16.45 g |
| 8 tsp | 18.8 g |
| 9 tsp | 21.15 g |
| 10 tsp | 23.5 g |
| 11 tsp | 25.85 g |
| 12 tsp | 28.2 g |
The tablespoon figures are included too, because most recipes switch between teaspoons and tablespoons, and 3 teaspoons make 1 tablespoon.
| Tablespoons | Grams (approx.) |
|---|---|
| 1 tbsp | 7.1 g |
| 2 tbsp | 14.1 g |
| 3 tbsp | 21.2 g |
| 4 tbsp | 28.2 g |
| 5 tbsp | 35.3 g |
| 6 tbsp | 42.4 g |
| 7 tbsp | 49.4 g |
| 8 tbsp | 56.5 g |
| 9 tbsp | 63.6 g |
| 10 tbsp | 70.6 g |
| 11 tbsp | 77.7 g |
| 12 tbsp | 84.8 g |
| 13 tbsp | 91.8 g |
| 14 tbsp | 98.9 g |
| 15 tbsp | 105.9 g |
| 16 tbsp | 113 g |
One tablespoon is one sixteenth of a cup, so every tablespoon figure is the cup weight divided by 16, rounded to one decimal place.
Cups to grams for reference
When a recipe jumps from spoons to cups, use this table instead of counting out 16 tablespoons. Every figure is the cup weight multiplied by the fraction, rounded to one decimal place, and all figures are approximate.
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 28.2 g |
| 1/3 cup | 37.7 g |
| 1/2 cup | 56.5 g |
| 2/3 cup | 75.3 g |
| 3/4 cup | 84.8 g |
| 1 cup | 113 g |
One cup of walnuts weighs 113 g, so a quarter cup is 28.2 g and half a cup is 56.5 g. Those two figures cover most everyday scaling, and the full table above covers the rest.
How the measurement works
The figure on this page comes from King Arthur Baking, measured spooned and levelled. Spoon the walnuts into the measuring spoon and level it off with the back of a knife. A cup of walnuts weighs 113 g, which is where the teaspoon figure of 2.35 g comes from. How the pieces are cut decides how much fits: whole pieces leave air gaps, chopped pieces pack tighter, and ground pieces pack tighter still, so the same spoon can weigh noticeably different amounts. The figures here assume the pieces as sold, spooned loosely and levelled, and if you chop them first, weigh them instead, because a spoon of chopped pieces is heavier than a spoon of whole ones.
All results on this page are approximate. Ingredient weights vary with brand, humidity, temperature and how firmly you pack the spoon, so when a recipe has to work the first time, weigh the ingredient on a kitchen scale and use the numbers here as a guide. The method matters more than the number itself, because the same spoon of walnuts measured two different ways can give two different weights, and the King Arthur Baking value assumes the spooned and levelled method every time.
Worked examples
Topping a bowl of porridge
A bowl of porridge for one takes 2 teaspoons (4.7 g) of walnuts scattered over the top, which adds crunch and richness without turning breakfast into a heavy meal. Chop larger pieces roughly first so the topping spreads evenly, and level the spoon so the amount is the same each morning. If you top porridge for the whole family, weigh the topping rather than counting spoons, because pieces vary in size and a spoon of large pieces weighs less than a spoon of small ones.
A batch of cookies
A batch of cookies uses 6 teaspoons (14.1 g) of walnuts folded into the dough, which is 2 tablespoons or 14.12 g, and the pieces should be spread evenly so every cookie gets some. Too many and the cookies fall apart; too few and the flavour disappears. Weigh the pieces for baking, because the recipe was written by weight even when it gives a spoon measure, and a scale removes the guesswork about piece size.
A trail mix for a walk
A small bag of trail mix for one person uses 4 teaspoons (9.4 g) of walnuts mixed with dried fruit and seeds, which is enough for a snack without becoming a meal. Measure the mix by weight when you make a large batch, because a spoon measure of mixed pieces is unreliable: the small pieces settle to the bottom and the large ones sit on top. Store the mix in a sealed jar and it keeps for weeks, which makes it a useful thing to make in bulk.
Practical guidance
Measuring nuts and seeds by the spoon
Spoon the walnuts into the measure and level it off with the back of a knife. How the pieces are cut decides how much fits: whole pieces leave air gaps, chopped pieces pack tighter, and ground pieces pack tighter still. The figures here assume the pieces as sold, spooned loosely and levelled, and if you chop them first, weigh them instead, because a spoon of chopped pieces is heavier than a spoon of whole ones.
Common mistakes with nuts and dried fruit
The most common mistake is measuring chopped pieces with a figure meant for whole ones, which over-measures by a noticeable amount. Another is using stale nuts straight from the back of the cupboard; taste one first, because rancid nuts ruin a whole batch. A third is adding dried fruit to a batter without tossing it in a little flour first, so it sinks to the bottom of the cake instead of staying spread through the crumb.
Scaling and when to weigh
Scaling with spoons is easy once you know the weight of one spoon. To measure 100 g of walnuts, count out about 42.6 teaspoons, and for 50 g, about 21.3 teaspoons. Halving a recipe that calls for 4 teaspoons means using 2 teaspoons, or 4.7 g, and doubling it means 8 teaspoons, or 18.8 g. For anything over a few spoonfuls, weigh the ingredient on a scale, because pieces vary in size and a spoon of large pieces weighs less than a spoon of small ones.
Storage. Refrigerate or freeze; walnut oils turn rancid quickly.
- Level every spoon with the back of a knife.
- Use spoons for small amounts, and a scale for large ones.
- Keep the same spoon for the whole recipe so errors stay consistent.
Frequently asked questions
How many grams is 1 teaspoon of walnuts?
One level teaspoon of walnuts weighs approximately 2.35 g. That figure comes from dividing the cup weight of 113 g by 48, and it assumes the ingredient is measured spooned and levelled. All figures on this page are approximate, so verify with a kitchen scale when it matters.
How many teaspoons of walnuts make 100 g?
About 42.6 teaspoons of walnuts weigh 100 g, and about 21.3 teaspoons weigh 50 g. Count out the spoons level, and switch to a scale for large amounts, since counting dozens of spoonfuls invites mistakes.
How many teaspoons of walnuts are in a tablespoon?
There are 3 teaspoons in 1 tablespoon, so 1 tablespoon of walnuts weighs approximately 7.1 g, which is three times the teaspoon weight of 2.35 g. Use the tablespoon table on this page when a recipe switches between the two units.
Does a heaped teaspoon of walnuts weigh more?
Yes, a heaped teaspoon weighs noticeably more than a level one, and the difference is biggest for light, fluffy ingredients. Always level the spoon with the back of a knife unless the recipe specifically says heaped, because recipes that give spoon measures assume a level spoon.
Do chopped walnuts weigh the same per spoon as whole?
No. Chopped pieces pack tighter than whole ones, so a spoon of chopped walnuts weighs more than a spoon of whole pieces. The figures on this page assume the pieces as sold, spooned loosely and levelled, so weigh the ingredient if you chop it first.
How should I store walnuts?
Refrigerate or freeze; walnut oils turn rancid quickly. Keeping it stored properly also keeps its weight consistent, since an ingredient that has absorbed moisture or dried out will not weigh the same per spoon as a fresh one.
