One ounce of orange juice is 0.11431259 cups, so converting ounces of orange juice to cups means multiplying by 0.11431259. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
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.
One cup of orange juice is 8.748 oz. US kitchen scales usually step in eighths of an ounce, which is 3.54 g — around 1.43% of a cup of this ingredient, so the scale is precise enough for a full cup and coarse for a spoonful. That is why recipes mix the two systems: ounces for the bulk, spoons for the small amounts.
What the number depends on: The dissolved sugar puts it just above water, which is why a hydrometer can read juice strength at all.
The formula
ounces- The amount of orange juice you are converting, in ounces
0.114312593246- Cups per ounce for orange juice, from its density of 1.0482 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in ounces.
- It is multiplied by 0.114312593246, the cups-per-ounce figure for orange juice.
- 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
2 oz of orange juice in cups
Take 2 oz of orange juice: 2 × 0.11431259 gives 0.228625 cups. Doubling the batch takes it to 0.45725 cups, because the relationship is a straight proportion once the density is known.
4 oz of orange juice in cups
4 oz of orange juice weighs out at 0.45725 cups. Divide 0.45725 by 0.11431259 and you get back to 4 oz, which is the quickest check that the factor is the right way up.
12 oz of orange juice in cups
12 oz of orange juice weighs out at 1.37175 cups. Divide 1.37175 by 0.11431259 and you get back to 12 oz, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many cups are in 1 oz of orange juice?
One ounce of orange juice is 0.11431259 cups. Half that quantity is 0.0571563 cups and double it is 0.228625 cups, 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 much does 2 cup of orange juice weigh?
2 cup of orange juice comes to 496 g, or 17.496 ounces. This page runs that calculation in reverse — enter a weight and it returns the volume — and the cups-to-ounces page does it in the direction the question is usually asked.
