To convert grams of powdered gelatin into cups, multiply by 0.0066666667: one gram comes to 0.0066666667 cups. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Put next to water — 1 g per mL exactly — powdered gelatin measures 0.63401 g per mL. That ratio, 63.4%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A cup of powdered gelatin is 150 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 135 g and 180 g covers the range from lightly spooned to firmly packed. That 20% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.667% of a cup of powdered gelatin, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 3.333 cups, and a 1 kg pack 6.667.
The condition this weight assumes: Unflavoured. A standard envelope is 7 g, which is a little over two and a quarter teaspoons.
The formula
grams- The amount of powdered gelatin you are converting, in grams
0.00666666666667- Cups per gram for powdered gelatin, from its density of 0.63401 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.00666666666667, the cups-per-gram figure for powdered gelatin.
- The result appears in cups, with a second reading in tbsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of powdered gelatin in cups
A recipe calling for 50 g of powdered gelatin needs 0.333333 cups on the scale. The arithmetic is 50 × 0.0066666667 = 0.33333333, and halving the recipe halves the weight to 0.166667 cups.
150 g of powdered gelatin in cups
A recipe calling for 150 g of powdered gelatin needs 1 cups on the scale. The arithmetic is 150 × 0.0066666667 = 1, and halving the recipe halves the weight to 0.5 cups.
500 g of powdered gelatin in cups
500 g of powdered gelatin weighs out at 3.33333 cups. Divide 3.33333 by 0.0066666667 and you get back to 500 g, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many cups are in 1 g of powdered gelatin?
One gram of powdered gelatin is 0.0066666667 cups. Half that quantity is 0.00333333 cups and double it is 0.0133333 cups, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of powdered gelatin not 236 g like water?
Because weight per cup depends on what is in the cup. Powdered gelatin has a density of 0.63401 g per mL where water has 1.00, so a cup of it weighs 150 g rather than 236.6 g. That is a difference of 86.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of powdered gelatin by roughly 20% — about 15 g either side of 150 g — because unflavoured. Weighing removes the question entirely.
Is a fluid ounce of powdered gelatin the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of powdered gelatin weighs 0.6614 oz, so the two readings differ by 33.9%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of powdered gelatin would weigh 158.5 g instead of 150 g — 8.5 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
A scale, if the result matters. Volume measuring carries a spread of about 20% for powdered gelatin — roughly 30 g on a 150 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How much does 2 cup of powdered gelatin weigh?
2 cup of powdered gelatin comes to 300 g, or 300 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the cups-to-grams page does it in the direction the question is usually asked.
