1/4 Cup Walnuts in Grams
1/4 cup of walnuts weighs 28.2 g (spooned and levelled, King Arthur Baking). Chopped walnut pieces with a rich, slightly bitter flavour. All the figures on this page are approximate conversions based on the King Arthur Baking value of 113 g per cup, so when a recipe really matters, verify with a kitchen scale.
Why a quarter cup is worth weighing
It is tempting to eyeball a quarter cup and move on, but a quarter cup is where volume measuring is at its worst. Small cups pack differently from large ones, a heaped measure is easily a third over, and the ingredient itself — how fine it is ground, how damp it is, how settled the jar is — changes what fits in the cup. Grams cut through all of that: the weighed amount is the same whatever the brand, the humidity or the size of your measuring cup.
Spooned and levelled is the method behind the number, and it matters. Walnuts is used for brownies, salads, pesto and banana bread. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Grams cut through all of that: 28.2 g of walnuts is 28.2 g whatever the brand, the humidity or the size of your measuring cup.

The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of walnuts weighs about 7.1 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 1/4-cup row outwards: every row is the cup weight times the fraction, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Spooned and levelled means the ingredient is measured the way King Arthur Baking measures it: spooned and levelled. For walnuts, that gives 113 g per cup, and a quarter of that is 28.2 g. The source for the figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Worked examples
A mini banana bread
A mini banana bread baked in a small loaf tin uses 1/4 cup of walnuts — 28.2 g — chopped and folded through the batter. The walnuts stay crunchy against the soft crumb, which is the contrast that makes banana bread worth eating. Weigh 28.2 g, chop them coarse, and toss them in a spoonful of flour before folding them in, so they do not sink to the bottom of the tin.
A salad for two
A salad for two people uses 1/4 cup of walnuts, 28.2 g, toasted in a dry pan and scattered over the leaves with blue cheese and pear. Toasting is the step that matters: raw walnuts taste flat and slightly bitter, while toasted walnuts are rich and nutty. Weigh them, toast them for three minutes, and let them cool before they go on the salad, or the heat wilts the leaves.
A small jar of pesto
A small jar of walnut pesto uses 1/4 cup of walnuts, 28.2 g, blended with basil, parmesan, garlic and olive oil. Walnut pesto is cheaper than pine nut pesto and just as good — the walnuts give it a rich, slightly bitter depth that suits pasta and grilled vegetables. Weigh the nuts, toast them first, and blend the pesto in short bursts so the oil does not heat up and turn bitter.
When a quarter cup matters
The quarter cup is the measure of the careful cook: the test bake, the single serving, the small jar of seasoning, the sauce for two. In each of those cooks the ingredient is doing real work, and the amount decides the result. A scale turns a guess into a number you can repeat next week, which is the whole point of writing a recipe down in the first place.
Walnuts are the nut most likely to turn rancid in the cupboard, because their oils are delicate and oxidise quickly in warmth and light. A quarter cup — 28.2 g — is a small amount, and it is worth tasting one before you use a bag that has been open for a while: a rancid walnut tastes bitter and paint-like, and it will ruin a whole bake. Keep walnuts in the fridge or the freezer, sealed, and they will stay sweet for months.
Scaling a quarter cup up and down
Scaling from a quarter cup is straightforward once the base number is fixed — the table above does the work, but the pattern is worth knowing by heart. Doubling a recipe that calls for 1/4 cup means weighing 56.4 g; halving it means 14.1 g, which is 2 tablespoons. A full cup is 113 g, and two cups is 226 g. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 28.2 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with walnuts
- Using walnuts straight from a warm cupboard without tasting one. Rancid walnuts ruin a bake and cannot be fixed. Taste first, and store the bag in the fridge.
- Folding walnuts into a batter without flouring them. The nuts sink to the bottom of the tin. Toss the weighed nuts in a spoonful of flour before folding them in.
- Scooping the cup through the bag or jar. Scooping packs the ingredient down and can add a fifth or more to the weight. Spoon it in lightly and level it off with a knife.
- Measuring over the mixing bowl. Levelling over the bowl drops the excess straight into the batter, so you have added ingredient you did not intend. Level over the bag or the sink.
Storage and handling
Refrigerate or freeze; walnut oils turn rancid quickly. Keeping walnuts stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag or jar has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. Label the container with the conversion — 1/4 cup is 28.2 g — and the next person to cook with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of walnuts?
1/4 cup of walnuts weighs 28.2 g, measured spooned and levelled according to King Arthur Baking. That is one quarter of the full-cup weight of 113 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
How many tablespoons is 1/4 cup of walnuts?
There are 4 tablespoons in a quarter cup, whatever the ingredient. One tablespoon of walnuts weighs about 7.1 g, so 4 tablespoons come to about 28.2 g. For small amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
How do I measure 1/4 cup of walnuts without a scale?
Walnuts is measured spooned and levelled, according to King Arthur Baking. Spoon it into a 1/4-cup measure, level the top with the back of a knife, and you will be close to 28.2 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good flour and removes the guesswork from every recipe, not just this one.
What is walnuts used for?
Brownies, salads, pesto and banana bread. Chopped walnut pieces with a rich, slightly bitter flavour. A quarter cup — 28.2 g — is a common amount in small batches, sauces, dressings and test bakes, which is why this conversion comes up so often.
Can I use walnuts instead of pecans?
Yes, at the same weight: 28.2 g of walnuts replaces 28.5 g of pecans near enough, and the two nuts are close cousins in flavour. Walnuts are slightly more bitter, pecans slightly sweeter, so taste the dish and adjust the sugar if it matters.
How do I toast 1/4 cup of walnuts?
Tip 28.2 g of walnuts into a dry frying pan over medium heat and shake the pan for 3 minutes, until they smell nutty and look a shade darker. Tip them out straight away — they keep cooking in the hot pan — and let them cool before chopping or eating.
