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 a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 500.40 g, based on rolled oats having a density of 90g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 90 (grams per cup for rolled oats). For 5.56 cups: 5.56 × 90 = 500.40 g.
For the most accurate results, weigh rolled oats 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: 500.40 g ÷ 90 = 5.56 cups. Or use the Grams to Cups converter.
