Formula and Step-by-Step

cups × 245g/cup ÷ 28.3495g/oz = ounces
  1. Start with 1 cup of tomato sauce
  2. 1 cup of tomato sauce = 245g
  3. 1 × 245 = 245g
  4. Convert grams to ounces: 245 ÷ 28.3495 = 8.64 oz

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

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 8.64 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 1 cup: 1 × 245 = 245g, then 245 ÷ 28.3495 = 8.64 oz.
