1/2 Cup Barley Flour in Grams

1/2 cup of barley flour weighs 42.5 g (spooned and levelled, King Arthur Baking). A full cup weighs 85 g, so the half cup is exactly half of that. Mild, slightly sweet flour from hulled barley. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale.

Why weighing barley flour beats measuring it in cups

Half a cup of barley flour weighs just 42.5 g, the lightest of the half-cup flours on this page alongside chickpea flour, because it is finely ground hulled barley and the particles are light and fluffy. Barley flour has a mild, slightly sweet flavour that suits breads, pancakes and cookies, and it is usually blended with wheat flour rather than used alone, because it has very little gluten and a loaf made with barley flour alone will be dense. The usual blend is one part barley flour to three parts wheat flour, and the ratio matters: too much barley and the loaf is heavy, too little and the barley flavour disappears.

Half a cup is the amount in a small batch of pancakes, a few cookies, or a loaf where barley flour is the flavouring rather than the structure. Barley flour absorbs more water than wheat flour, so a batter or dough made with it may need a little more liquid, and it gives bakes a tender, slightly sweet crumb. Weighing the flour is essential, because the weight difference between barley flour and wheat flour is large: a half cup of barley flour is 42.5 g and a half cup of wheat flour is 60 g, so swapping them cup for cup leaves the recipe short on flour by nearly a third.

Barley Flour cups to grams conversion table

Cups Grams Tablespoons
1/8 cup 10.6 g 2
1/4 cup 21.2 g 4
1/3 cup 28.3 g 5.3
1/2 cup 42.5 g 8
2/3 cup 56.7 g 10.7
3/4 cup 63.8 g 12
1 cup 85 g 16
1 1/2 cups 127.5 g 24
2 cups 170 g 32
3 cups 255 g 48

The table is built around the half cup, which is the measure this page is about, with the full-cup weight of 85 g as the anchor. Every row is the full-cup weight multiplied by the fraction, so the numbers stay consistent as you scale up or down. One tablespoon of barley flour weighs about 5.3 g, which is useful when a recipe calls for a spoonful rather than a cup.

Worked examples

Barley pancakes for two

Pancakes for two people use about 1/2 cup of barley flour, which is 42.5 g, mixed with white flour, an egg, milk and baking powder. Weigh 42.5 g rather than measuring by cups, because barley flour is light and a scooped half cup can be 10 g heavy. The pancakes will be tender and lightly sweet, with a mild maltiness that suits maple syrup.

Barley cookies, a batch of 12

A batch of 12 cookies uses about 1/2 cup of barley flour, which is 42.5 g, mixed with white flour, butter, sugar and raisins. Weigh the flour so the cookies are tender rather than dry: barley flour makes a softer cookie than wheat flour, and the amount decides whether they hold together or crumble. Bake until the edges are set but the centres are still soft.

A small barley loaf for two

A small loaf for two people uses about 1/2 cup of barley flour, which is 42.5 g, mixed with 1 1/2 cups of white bread flour, water, yeast and salt. Weigh 42.5 g so the blend is exact: too much barley and the loaf is dense, too little and the barley flavour is lost. The loaf will be mildly sweet and tender, with a soft crumb.

How the weight was measured

How you fill the cup decides what the cup weighs. The method used here is spooned and levelled: the ingredient is spooned into the cup and levelled with a straight edge, never scooped and never tapped down. If you scoop, you compress the ingredient and the same cup can weigh noticeably more, which is the single most common reason a recipe that worked for its author fails in another kitchen.

The value is taken from King Arthur Baking with high confidence. King Arthur Baking is the reference used across this site because its chart is consistent and widely used by recipe developers. No other source was mixed in, and nothing on this page was estimated from a different ingredient. Remember that every conversion on this page is approximate: check the weight on a kitchen scale whenever accuracy matters, and use the table as a guide rather than a guarantee.

Practical guidance

Store barley flour in an airtight container in a cool, dry place for up to 6 months, because it contains oils that go rancid. Always spoon the flour into the cup and level it, never scoop, because barley flour is light and fluffy and compresses easily. Blend barley flour with wheat flour rather than using it alone, usually one part barley to three parts wheat, and weigh both flours so the ratio is exact. Barley flour absorbs more water than wheat flour, so a dough or batter made with it may need a little more liquid. If you do not have a scale, spoon the flour loosely into the half cup and level it, remembering that the 42.5 g figure is approximate.

Common mistakes with half-cup measures

The most common mistake is treating a half cup as a casual measure. Half a cup of flour is 60 g, and a scooped half cup can easily weigh 70 g or more, which is a 15 percent error in a recipe that may only contain two or three cups of flour in total. Small measures carry the largest relative errors, so weighing matters more, not less, at this size. The second mistake is using a liquid measuring jug for dry flour: the meniscus line is designed for liquids, and flour measured in a jug is almost always over- or under-filled. Use a dry cup, or a scale. The third is assuming every flour weighs the same per half cup: the flours on this page range from about 42 g to about 82 g per half cup, so swapping flours cup for cup without adjusting the weight changes the recipe. Finally, do not pack flour into the half cup to make it look full: spoon and level, every time.

Frequently asked questions

How many grams is 1/2 cup of barley flour?

1/2 cup of barley flour weighs 42.5 g when spooned and levelled, according to King Arthur Baking, which lists 85 g per cup. The figure is approximate, because the light flour compresses easily, so verify with a kitchen scale when it matters.

Can I use barley flour on its own for bread?

Not usually. Barley flour has very little gluten, so a loaf made with barley flour alone will be dense. Blend it with wheat flour, usually one part barley to three parts wheat, and weigh both flours so the ratio is exact.

What does barley flour taste like?

Mild and slightly sweet, with a gentle maltiness that suits breads, pancakes and cookies. It is subtler than rye flour and less nutty than spelt, so it blends well without dominating the flavour.

Is barley flour gluten-free?

No. Barley contains gluten, though less than wheat, so barley flour is not suitable for people with coeliac disease. It is a good choice for anyone who wants a milder, sweeter flour without going gluten-free.

How many cups is 100 g of barley flour?

100 g of barley flour is about 1.18 cups, or just over 1 cup. At 85 g per cup, divide 100 by 85 to get the answer, and use a scale for the most accurate result.
