Formula and Step-by-Step

quarts × 980g/qt ÷ 28.3495g/oz = ounces
  1. Start with 1 quart of tomato sauce
  2. 1 quart of tomato sauce = 980g
  3. 1 × 980 = 980g
  4. Convert grams to ounces: 980 ÷ 28.3495 = 34.57 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.

Understanding the Units

What is a Quart?

The quart gets its name from "quarter" (of a gallon). One US quart is about 5.7% smaller than 1 liter (946 ml vs 1,000 ml). Always use the exact unit your recipe specifies.

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.
