Cups of orange juice to grams runs on one number, 248 grams per cup. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
Water is the yardstick: 1 mL of it weighs 1 g. Orange juice comes in at 1.0482 g per mL, or 104.8% of water, which is why a cup of it is 248 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A cup of orange juice is 248 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 246.8 g and 250.5 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 0.403% of a cup of orange juice, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.016 cups, and a 1 kg pack 4.032.
The condition this weight assumes: The dissolved sugar puts it just above water, which is why a hydrometer can read juice strength at all.
The formula
cups- The amount of orange juice you are converting, in cups
248- Grams per cup for orange juice, from its density of 1.0482 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in cups.
- It is multiplied by 248, the grams-per-cup figure for orange juice.
- 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 orange juice in grams
1/3 cup of orange juice weighs out at 82.6667 grams. Divide 82.6667 by 248 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 orange juice in grams
A recipe calling for 3/4 cup of orange juice needs 186 grams on the scale. The arithmetic is 0.75 × 248 = 186, and halving the recipe halves the weight to 93 grams.
3 cup of orange juice in grams
A recipe calling for 3 cup of orange juice needs 744 grams on the scale. The arithmetic is 3 × 248 = 744, and halving the recipe halves the weight to 372 grams.

Frequently asked questions
How many grams are in 1 cup of orange juice?
One cup of orange juice is 248 grams. Half that quantity is 124 grams and double it is 496 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of orange juice not 236 g like water?
Because weight per cup depends on what is in the cup. Orange juice has a density of 1.0482 g per mL where water has 1.00, so a cup of it weighs 248 g rather than 236.6 g. That is a difference of 11.4 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. Orange juice does not compress, so a cup of it is 248 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 orange juice 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 orange juice weighs 1.093 oz, so the two readings differ by 9.35%. 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 orange juice would weigh 262.06 g instead of 248 g — 14.1 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 orange juice — roughly 2.48 g on a 248 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 orange juice is 500 g?
500 g of orange juice is 2.0161 cups — 0.00403226 cups to one gram, so 500 × 0.00403226 = 2.0161. Going that way is a division by 248, or a multiplication by 0.00403226 if you prefer.
