Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 245g/cup = cups
  1. Start with 8 ounces of tomato sauce
  2. Convert ounces to grams: 8 × 28.35 = 226.80g
  3. 1 cup of tomato sauce = 245g
  4. 226.80g ÷ 245g/cup = 0.93 cups

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 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.

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.

Frequently Asked Questions

About 0.93 cups, 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.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 245 (grams per cup). For 8 ounces: 8 × 28.3495 = 226.80g, then 226.80 ÷ 245 = 0.93 cups.
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.
Temperature has a minimal effect on most cooking liquids. The density of tomato sauce changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 0.93 cups × 245g/cup = 226.80g, then 226.80g ÷ 28.3495 = 8 ounces. Or use the Cups to Ounces converter.
