How many cups is 5.3 oz?

5.3 fl oz = 0.66 cup

0.663 cups · 10.6 Tbsp · 157 mL

Measure with: about 2 × 1/3 cup · or spoons only: 10 Tbsp + 2 tsp

Check the label: on cans, jars and yogurt cups the “5.3 oz” is net weight, not fluid ounces, so the volume inside is different. See below.

The 5.3 oz on a single-serve cup of Greek yogurt is net weight: 150 g of yogurt. It is a weight label, so the volume inside is a separate question.

If 150 g were water, it would fill about 0.64 cup. Greek yogurt is thicker and slightly denser than water, so one cup holds a bit under 2/3 cup. For a smoothie or a marinade, call one cup "a scant 2/3 cup" and move on.

For baking, where yogurt replaces part of the liquid, weigh it if the recipe gives grams. If the recipe asks for 2/3 cup, spoon the yogurt into the dry 1/3 cup measure twice and level the top; one container may come up slightly short. The difference between net weight and volume is covered in dry vs. liquid ounces.
