To convert cups of vinegar into grams, multiply by 239: one cup comes to 239 grams. 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 1.0102 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of vinegar weighs 239 g, so this ingredient is 101% as heavy as the same volume of water — the single fact the whole page rests on.
A cup of vinegar is 239 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 237.8 g and 241.4 g covers the range from lightly spooned to firmly packed. That 1% 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 0.418% of a cup of vinegar, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.092 cups, and a 1 kg pack 4.184.
What the number depends on: Mostly water with 4 to 8% acetic acid, so its density is barely different from water.
The formula
cups- The amount of vinegar you are converting, in cups
239- Grams per cup for vinegar, from its density of 1.0102 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in cups.
- It is multiplied by 239, the grams-per-cup figure for vinegar.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
1/3 cup of vinegar in grams
1/3 cup of vinegar weighs out at 79.6667 grams. Divide 79.6667 by 239 and you get back to 1/3 cup, which is the quickest check that the factor is the right way up.
3/4 cup of vinegar in grams
Take 3/4 cup of vinegar: 0.75 × 239 gives 179.25 grams. Doubling the batch takes it to 358.5 grams, because the relationship is a straight proportion once the density is known.
3 cup of vinegar in grams
A recipe calling for 3 cup of vinegar needs 717 grams on the scale. The arithmetic is 3 × 239 = 717, and halving the recipe halves the weight to 358.5 grams.
How to read your score
Frequently asked questions
How many grams are in 1 cup of vinegar?
One cup of vinegar is 239 grams. Half that quantity is 119.5 grams and double it is 478 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of vinegar not 236 g like water?
Because weight per cup depends on what is in the cup. Vinegar has a density of 1.0102 g per mL where water has 1.00, so a cup of it weighs 239 g rather than 236.6 g. That is a difference of 2.4 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?
Barely. Vinegar does not compress, so a cup of it is 239 g however it is poured — within about 1%, which is inside the accuracy of a domestic scale. This is the group where measuring by volume is defensible.
Is a fluid ounce of vinegar 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 vinegar weighs 1.054 oz, so the two readings differ by 5.38%. 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 vinegar would weigh 252.55 g instead of 239 g — 13.5 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 1% for vinegar — roughly 2.39 g on a 239 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 many cups of vinegar is 500 g?
500 g of vinegar is 2.0921 cups — 0.0041841 cups to one gram, so 500 × 0.0041841 = 2.0921. Going that way is a division by 239, or a multiplication by 0.0041841 if you prefer.
