How Much Is 0.21 Cups of Granulated Sugar in Grams?

0.21 cups of granulated sugar weighs 42.00 g. This is based on granulated sugar having a density of 200g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 0.21 cups.

Formula and Step-by-Step

cups × 200g/cup = grams
  1. Start with 0.21 cups of granulated sugar
  2. 1 cup of granulated sugar = 200g
  3. 0.21 × 200 = 42g

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

Measuring Tip

Sugar is one of the easier dry ingredients to measure by volume because the crystals pack relatively consistently compared to flour or cocoa powder.

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?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 42.00 g, based on granulated sugar having a density of 200g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 200 (grams per cup for granulated sugar). For 0.21 cups: 0.21 × 200 = 42.00 g.
For the most accurate results, weigh granulated sugar 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.
Granulated and powdered sugars should be spooned into the measuring cup and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 42.00 g ÷ 200 = 0.21 cups. Or use the Grams to Cups converter.
