To convert cups of crumbled feta into ounces, multiply by 5.2910943: one cup comes to 5.2910943 ounces. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Water is the yardstick: 1 mL of it weighs 1 g. Crumbled feta comes in at 0.63401 g per mL, or 63.4% of water, which is why a cup of it is 150 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A cup of crumbled feta is 150 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 141 g and 168 g covers the range from lightly spooned to firmly packed. That 12% 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 crumbled feta is 5.291 oz. US kitchen scales usually step in eighths of an ounce, which is 3.54 g — around 2.36% 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: Drained and crumbled. Brine left clinging to it adds weight without adding any cheese.
The formula
cups- The amount of crumbled feta you are converting, in cups
5.29109429244- Ounces per cup for crumbled feta, from its density of 0.63401 g/mL
ounces- The equivalent quantity in ounces
How it works, step by step
- Enter the quantity in cups.
- It is multiplied by 5.29109429244, the ounces-per-cup figure for crumbled feta.
- The result appears in ounces, with a second reading in g 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 crumbled feta in ounces
1/3 cup of crumbled feta weighs out at 1.7637 ounces. Divide 1.7637 by 5.2910943 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 crumbled feta in ounces
Take 3/4 cup of crumbled feta: 0.75 × 5.2910943 gives 3.96832 ounces. Doubling the batch takes it to 7.93664 ounces, because the relationship is a straight proportion once the density is known.
3 cup of crumbled feta in ounces
A recipe calling for 3 cup of crumbled feta needs 15.8733 ounces on the scale. The arithmetic is 3 × 5.2910943 = 15.873283, and halving the recipe halves the weight to 7.93664 ounces.

Frequently asked questions
How many ounces are in 1 cup of crumbled feta?
One cup of crumbled feta is 5.2910943 ounces. Half that quantity is 2.64555 ounces and double it is 10.5822 ounces, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of crumbled feta not 236 g like water?
Because weight per cup depends on what is in the cup. Crumbled feta 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 crumbled feta by roughly 12% — about 9 g either side of 150 g — because drained and crumbled. Weighing removes the question entirely.
Is a fluid ounce of crumbled feta 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 crumbled feta 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 crumbled feta 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?
A scale, if the result matters. Volume measuring carries a spread of about 12% for crumbled feta — roughly 18 g on a 150 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 crumbled feta is 16 oz?
16 oz of crumbled feta is 3.0239 cups — 0.188997 cups to one ounce, so 16 × 0.188997 = 3.0239. Going that way is a division by 5.29109, or a multiplication by 0.188997 if you prefer.
