Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 185g/cup = cups
  1. Start with 2.04 ounces of rice (long grain)
  2. Convert ounces to grams: 2.04 × 28.35 = 57.83g
  3. 1 cup of rice (long grain) = 185g
  4. 57.83g ÷ 185g/cup = 0.31 cups

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

Measuring Tip

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 0.31 cups, based on rice (long grain) having a density of 185g 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 185 (grams per cup). For 2.04 ounces: 2.04 × 28.3495 = 57.83g, then 57.83 ÷ 185 = 0.31 cups.
For the most accurate results, weigh rice (long grain) on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 0.31 cups × 185g/cup = 57.83g, then 57.83g ÷ 28.3495 = 2.04 ounces. Or use the Cups to Ounces converter.
