20g Parmesan to Cups

20 grams of parmesan is a small amount, best measured with a spoon rather than a full cup. At 100g per cup, it works out to 3.2 tablespoons.

20 grams of parmesan = 0.20 cups (¼ cup / 3.2 tbsp / 9.6 tsp)

Parmesan has a density of approximately 100g per cup. Finely grated: 100g. Coarsely grated runs closer to 80g per cup. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.

The Math for 20g of Parmesan

cups = grams ÷ grams per cup

20g divided by 100g (the weight of one cup of parmesan) equals 0.20 cups. Multiplying that by 16 gives 3.2 tablespoons, and by 48 gives 9.6 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.

Parmesan is lighter than water, which weighs about 236g per cup. That's why 20g of parmesan takes up more volume (47ml) than the same weight of water would (20ml). For a side-by-side look at how other ingredients compare, see the 20 grams to cups page.

Metric and Imperial Cup Sizes

The 0.20 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 20g, that's ¼ metric cups or ⅛ imperial cups of parmesan, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.

Making More or Less Than 20g

Doubling a recipe that calls for 20g of parmesan means weighing 40g, or measuring 0.40 cups if you're working by volume instead of weight. Halving it means 10g, or 0.10 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.

How Parmesan Compares to Similar Ingredients

Within cheeses, density still varies by ingredient. At 20g, mozzarella cheese (113g per cup) measures ⅛ cup, while cheddar cheese (113g per cup) measures ⅛ cup, compared to ¼ cup for parmesan. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.

Frequently Asked Questions

What is 20 grams of parmesan in cups?+

20 grams of parmesan is 0.20 cups, or 3.2 tablespoons.

Should I use a spoon or a cup for 20g of parmesan?+

At 20g, a tablespoon or teaspoon measurement is usually more practical than a fractional cup. Use 3.2 tablespoons or 9.6 teaspoons.

Is 20 grams of parmesan the same as 20 milliliters?+

Only if it weighed the same as water. 20g of water is about 20ml, while 20g of parmesan is 47ml, because the two have different densities.

Does the answer change for a metric or imperial cup?+

Slightly. 20g of parmesan is ¼ metric cups or ⅛ imperial cups, close to the US figure but not identical, since each standard defines the cup at a different volume.
