Formula and Step-by-Step

cups × 245g/cup ÷ 28.3495g/oz = ounces
  1. Start with 0.33 cups of tomato sauce
  2. 1 cup of tomato sauce = 245g
  3. 0.33 × 245 = 80.85g
  4. Convert grams to ounces: 80.85 ÷ 28.3495 = 2.85 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

Frequently Asked Questions

About 2.85 oz, based on tomato sauce 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 cups by 245 (grams per cup for tomato sauce), then divide by 28.3495 to convert grams to ounces. For 0.33 cups: 0.33 × 245 = 80.85g, then 80.85 ÷ 28.3495 = 2.85 oz.
For the most accurate results, weigh tomato sauce on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
