To convert ounces of plain yogurt into cups, multiply by 0.11571234: one ounce comes to 0.11571234 cups. 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 1.0356 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of plain yogurt weighs 245 g, so this ingredient is 103.6% as heavy as the same volume of water — the single fact the whole page rests on.
A cup of plain yogurt is 245 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 243.8 g and 247.4 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.
One cup of plain yogurt is 8.642 oz. US kitchen scales usually step in eighths of an ounce, which is 3.54 g — around 1.45% 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.
The condition this weight assumes: Plain and unstrained. Greek yogurt is much thicker but only slightly heavier per cup.
The formula
ounces- The amount of plain yogurt you are converting, in ounces
0.115712339286- Cups per ounce for plain yogurt, from its density of 1.0356 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in ounces.
- It is multiplied by 0.115712339286, the cups-per-ounce figure for plain yogurt.
- 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 plain yogurt in cups
2 oz of plain yogurt weighs out at 0.231425 cups. Divide 0.231425 by 0.11571234 and you get back to 2 oz, which is the quickest check that the factor is the right way up.
4 oz of plain yogurt in cups
4 oz of plain yogurt weighs out at 0.462849 cups. Divide 0.462849 by 0.11571234 and you get back to 4 oz, which is the quickest check that the factor is the right way up.
12 oz of plain yogurt in cups
12 oz of plain yogurt weighs out at 1.38855 cups. Divide 1.38855 by 0.11571234 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 plain yogurt?
One ounce of plain yogurt is 0.11571234 cups. Half that quantity is 0.0578562 cups and double it is 0.231425 cups, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of plain yogurt not 236 g like water?
Because weight per cup depends on what is in the cup. Plain yogurt has a density of 1.0356 g per mL where water has 1.00, so a cup of it weighs 245 g rather than 236.6 g. That is a difference of 8.4 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. Plain yogurt does not compress, so a cup of it is 245 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 plain yogurt 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 plain yogurt weighs 1.08 oz, so the two readings differ by 8.03%. 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 plain yogurt would weigh 258.89 g instead of 245 g — 13.9 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 plain yogurt — roughly 2.45 g on a 245 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 plain yogurt weigh?
2 cup of plain yogurt comes to 490 g, or 17.284 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.
