To convert grams of powdered gelatin into millilitres, multiply by 1.5772549: one gram comes to 1.5772549 millilitres. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
The density behind that figure is 0.63401 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of powdered gelatin weighs 150 g, so this ingredient is 63.4% as heavy as the same volume of water — the single fact the whole page rests on.
Powdered gelatin has a density of 0.63401 g per mL, so 100 mL of it weighs 63.4 g and 250 mL weighs 158.5 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 63.4% as heavy as the same volume of water.
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.
What the number depends on: 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
1.57725491- Millilitres per gram for powdered gelatin, from its density of 0.63401 g/mL
millilitres- The equivalent quantity in millilitres
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 1.57725491, the millilitres-per-gram figure for powdered gelatin.
- The result appears in millilitres, with a second reading in tsp 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 millilitres
50 g of powdered gelatin weighs out at 78.8627 millilitres. Divide 78.8627 by 1.5772549 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of powdered gelatin in millilitres
150 g of powdered gelatin weighs out at 236.588 millilitres. Divide 236.588 by 1.5772549 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of powdered gelatin in millilitres
A recipe calling for 500 g of powdered gelatin needs 788.627 millilitres on the scale. The arithmetic is 500 × 1.5772549 = 788.62745, and halving the recipe halves the weight to 394.314 millilitres.

Frequently asked questions
How many millilitres are in 1 g of powdered gelatin?
One gram of powdered gelatin is 1.5772549 millilitres. Half that quantity is 0.788627 millilitres and double it is 3.15451 millilitres, 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?
At this size the spoon wins. One millilitre of powdered gelatin is 0.634 g, and a scale reading to the nearest gram is working at 158% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How much does 15 mL of powdered gelatin weigh?
15 mL of powdered gelatin comes to 9.5102 g, or 9.5102 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the ml-to-grams page does it in the direction the question is usually asked.
