Frequently Asked Questions

About 3.24 oz, based on yogurt having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 5.10 (grams per teaspoon for yogurt), then divide by 28.3495 to convert grams to ounces. For 18 teaspoons: 18 × 5.10 = 91.88g, then 91.88 ÷ 28.3495 = 3.24 oz.
For the most accurate results, weigh yogurt on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.
