Grated Parmesan cheese weighs 100 grams per cup — the lightest cheese figure on this site — reflecting how finely it's typically grated and how hard and dry aged Parmesan is to begin with, packing in far less mass per cup than a softer, moister cheese like shredded cheddar despite Parmesan's reputation as a dense, concentrated cheese by weight.
Genuine Parmigiano-Reggiano (a protected European designation requiring specific aging, region, and production methods, typically 12-36+ months) is a meaningfully different product from generic domestic "parmesan cheese" sold in the US, which isn't held to the same aging or production standards and generally has a milder, less complex flavor.
The shelf-stable canned or shaker-jar "parmesan cheese" sold in the pasta aisle is a different product still — pre-grated, often blended with anti-caking agents like cellulose, and typically pasteurized in a way that changes both flavor and melting behavior compared to fresh-grated Parmesan cut from a wedge, which this site's conversion figure represents.
Grated parmesan's 100g-per-cup weight is considerably lighter than a soft shredded cheese because parmesan is aged and low-moisture, grating into fine, airy strands that pack loosely — pre-shredded, coarser parmesan sold in tubs can weigh meaningfully more per cup than freshly grated, finely powdered parmesan, so recipes calling for parmesan by volume carry more built-in variability than most cheese conversions on this site.
Genuine Parmigiano-Reggiano, aged a minimum of 12 months under strict Italian regulation, has a noticeably more complex, crystalline texture than generic "parmesan" sold pre-grated in a shaker can — a real quality distinction that doesn't show up in the conversion figure but affects flavor considerably.
The rind isn't waste — it's commonly simmered in soups and sauces for extra savory depth, then removed before serving.

Frequently asked questions
Is Parmigiano-Reggiano the same as generic "parmesan cheese"?
No — Parmigiano-Reggiano carries a legally protected designation tied to specific Italian regions, production rules, and a minimum aging period (often well past a year), while a domestic cheese simply labeled "parmesan" isn't bound by any of that and tends to taste noticeably simpler and milder by comparison.
Does the shelf-stable canned parmesan in the pasta aisle use the same conversion figure?
Not reliably — canned or shaker-jar parmesan is pre-grated, often blended with anti-caking cellulose, and processed differently than fresh-grated Parmesan cut from a wedge, which is what this site's 100g/cup figure represents; the canned product can pack somewhat differently.
Why does Parmesan weigh so little per cup compared to other cheeses?
It's grated very fine and is an exceptionally hard, dry, aged cheese to begin with — both the fine grate and the low moisture content mean a cup holds relatively little actual cheese mass compared to a softer, moister shredded cheese.
Can I substitute pre-grated Parmesan for freshly grated in a recipe?
It works, though freshly grated Parmesan generally has better flavor and melts more smoothly, since pre-grated versions often include anti-caking additives that can slightly affect texture, especially in a sauce meant to be silky rather than grainy.
How long does grated Parmesan last once opened?
About 3-4 weeks refrigerated after opening — considerably longer than a softer cheese like shredded cheddar, thanks to Parmesan's low moisture content and extensive aging, both of which make it naturally more resistant to spoilage.
