Formula and Step-by-Step

cups × 140g/cup = grams
  1. Start with 1 cup of sunflower seeds
  2. 1 cup of sunflower seeds = 140g
  3. 1 × 140 = 140g

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

Mental Math Shortcut

For 1 cup of sunflower seeds, just remember: 140g. Double it for 2 cups (280g), halve it for a half cup (70g).

Measuring Tip

Sunflower seeds are small and pack tightly. Pour them into the measuring cup and level off without shaking, which settles the seeds and increases the weight.

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 140.00 g, based on sunflower seeds having a density of 140g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 140 (grams per cup for sunflower seeds). For 1 cup: 1 × 140 = 140.00 g.
For the most accurate results, weigh sunflower seeds 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: 140.00 g ÷ 140 = 1 cup. Or use the Grams to Cups converter.
