1 Cup Ginger in Grams
1 cup of ginger weighs 86 g (spooned and levelled, USDA). Dried, ground ginger root; hotter and more concentrated than fresh. All the figures on this page are approximate conversions based on the USDA value, so when a recipe really matters, verify with a kitchen scale.
Ground ginger is dried ginger root ground to a fine powder, and a cup of it weighs only 86 g, which makes it one of the lightest ground spices per cup. It is hotter and more concentrated than fresh ginger, because drying removes the water and leaves the flavour compounds behind, so a teaspoon of ground ginger carries far more heat than a teaspoon of fresh ginger. It is used in baking, curries, stir-fries and teas, where its warmth is the point of the dish. It keeps for up to a year in an airtight jar, but it loses its heat steadily, so a jar that has been open for a year will taste noticeably milder than a fresh one.
Cups lie: why ginger should be weighed
Dry pantry ingredients are the ones where a scale earns its keep fastest, because the amounts are small and the consequences are large. A teaspoon of baking soda is only about 6 g, but the difference between the right amount and double the amount is the difference between a cake that rises and one that tastes of soap and collapses. Spices are even more concentrated: a tablespoon of ground ginger weighs about 5 g, and that is enough to flavour a whole batch of biscuits. Nuts and dried fruit sit at the other end of the scale, where a cup is a substantial amount and the weight depends on how whole, chopped or packed the pieces are. Weighing dry ingredients is the only way to be consistent with small amounts, because a heaped spoon and a level spoon can differ by half.
Worked examples
A gingerbread batch
A gingerbread that calls for 1/4 cup of ground ginger needs 21.5 g, mixed with flour, cinnamon and cloves. The ginger is the dominant spice in gingerbread, and its weight matters because too little leaves the biscuits bland and too much makes them harsh and burning. Weigh 21.5 g, mix the spices into the flour before adding the wet ingredients, and the flavour will be even throughout the batch.
A curry spice mix
A curry spice mix that uses 2 tablespoons of ground ginger needs 10.8 g, blended with cumin, coriander and turmeric. The ginger gives the mix its warmth and its bite, and it should be added to the pan with the other ground spices and fried briefly in oil before the liquid goes in, which blooms the flavour. Weigh the ginger rather than measuring by eye, because a heaped tablespoon of ground ginger can weigh half as much again as a level one.
A warming tea blend
A tea blend that calls for 1 tablespoon of ground ginger needs 5.4 g, mixed with dried lemon peel and honey. The ginger gives the tea its heat and its soothing warmth, and it dissolves readily in hot water. Use ground ginger rather than fresh ginger for a tea blend, because it stores well and the flavour is consistent from one cup to the next, and keep the blend in an airtight jar so the aroma does not fade.

One tablespoon of ginger weighs about 5.4 g, and a cup is 16 tablespoons, so the tablespoon column is simply the cup weight divided by 16. 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. All the values in this table are approximate, and they assume the ingredient is measured spooned and levelled, exactly as the source measured it.
How the weight was measured
The figure on this page comes from USDA, measured spooned and levelled unless the method line says otherwise. Spooning means filling the cup with a spoon rather than plunging the cup into the bag, and levelling means sweeping a knife across the rim. Scooping packs the ingredient down and can add a fifth or more to the weight, which is why two bakers following the same cup-based recipe can get visibly different results. Confidence in this value is medium. That reflects how consistent the ingredient is from brand to brand: a uniform, factory-packed ingredient is more predictable than a fresh, variable one. Even a high-confidence figure is still an approximation, because moisture, grind size and settling all shift the weight a little. Treat the grams on this page as a reliable starting point and check with a scale when the recipe is fussy, expensive, or being made for the first time.
When this conversion matters most
This conversion matters most with leavening, salt and spices, where the amounts are small and the effect is large. Baking soda, baking powder and yeast all work within narrow ranges, and too much or too little changes the rise, the flavour and the texture. It matters less with nuts and dried fruit in a trail mix or a salad, where a few grams either way is invisible. It matters again in bulk baking and preserving, where a spice blend or a leavening mix is made in quantity and a cup-based error is multiplied across dozens of batches. When the ingredient is the difference between rising and not rising, weigh it.
Common mistakes
The most common mistake is using a heaped spoon when the recipe means a level one. A heaped tablespoon of a ground spice can weigh half as much again as a level tablespoon, which is enough to make a curry bitter or a cake taste of baking soda. The second is scooping a dry ingredient straight from the jar with the measuring spoon, which packs it; spoon it in and level it with a knife instead. The third is measuring over the mixing bowl, so an overshoot falls in and cannot be taken out; measure over a plate or a piece of paper. And the fourth is confusing ingredients that look alike: baking soda and baking powder, ground ginger and ground cinnamon, salt and sugar. They weigh differently and behave differently, and a mix-up cannot be fixed after mixing.
What to do if you do not have a scale
If you do not have a scale, use proper measuring spoons for small amounts and level every spoon with the back of a knife. For cups of nuts, seeds or dried fruit, spoon the ingredient into a dry cup and level it, without pressing it down, because pressing packs the pieces and adds weight. For ground spices, spoon them in lightly and level them; do not tap the spoon, which settles the powder. For leavening and yeast, which are used in tiny amounts, a scale that reads to the gram is genuinely worth owning, because a single gram too much baking soda is noticeable in the finished cake.
Storing ginger
Airtight jar, cool and dark, up to 1 year. Keeping ginger properly stored matters for the conversion as well as for the flavour: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, and one that has dried out weighs less. Store it in an airtight container, away from heat and light, and measure it in the state the recipe expects, not straight from a damp or stale bag.
Frequently asked questions
What is the difference between ground ginger and fresh ginger?
Ground ginger is dried ginger root ground to a powder, and it is hotter and more concentrated than fresh ginger, because drying removes the water. A tablespoon of ground ginger weighs about 5 g and carries far more heat than a tablespoon of fresh ginger, which is mostly water. They are not interchangeable by volume: ground ginger suits baking and spice blends, where a dry, even heat is wanted, while fresh ginger suits stir-fries and curries, where its brightness and its texture matter.
How long does ground ginger keep?
Ground ginger keeps for up to a year in an airtight jar in a cool, dark place, but it loses its heat steadily over that time. A jar that has been open for a year will taste noticeably milder than a fresh one, and the colour will fade from bright yellow to dull beige. Taste it before using it in an important recipe, and replace it if the aroma is faint. Whole dried ginger keeps longer than ground ginger, so buy whole and grind it yourself if you use it often.
Can I use cups instead of a scale for ginger?
Yes, but a scale is more accurate. If you measure ginger spooned and levelled, exactly as the figure on this page was measured, a cup will be close to 86 g, within a few grams. The problem is that most people scoop rather than spoon, which can add 15 to 25 percent to the weight, and that error is enough to change a bake. For everyday cooking, cups are fine. For baking, where the ratio of ingredients decides the result, weigh it and check the number on the scale.
How many tablespoons are in a cup of ginger?
There are 16 tablespoons in a US cup, so a cup of ginger is 16 tablespoons, and one tablespoon weighs about 5.4 g. A teaspoon weighs about 1.8 g. Tablespoons are useful when a recipe calls for a small amount, but they carry the same packing problem as cups: a heaped tablespoon can weigh half as much again as a level one, so level every spoon with the back of a knife, and use a scale for small amounts when accuracy matters.
Does the weight change if I pack or sift ginger?
Yes, and this is the single biggest source of error in cup measurements. ginger is measured spooned and levelled, and a scooped cup can weigh 15 to 25 percent more than a spooned cup, because scooping packs the ingredient down. Sifting has the opposite effect: it adds air and makes the cup lighter. Always measure the way the figure on this page was measured, spooned and levelled, and the weight will match the table.
