How Many Grams in a Cup of Pumpkin Purée?
One cup of pumpkin purée weighs 245 grams — exactly the same as a cup of milk, and one of the most mistyped numbers in autumn baking, because the can on the shelf is not a cup or two cups. Below are the full conversion tables, a converter for any amount, and the can maths that fixes it.

How to measure pumpkin purée properly
Learn the can. The standard can of pumpkin purée is 15 ounces — 425 grams — which is 1¾ cups by this table, not the 2 cups many recipes assume. A recipe calling for 'one can' wants 425 grams; a recipe calling for 2 cups wants 490 grams, which is a can plus about 4 tablespoons (65 grams).
Purée is not pie mix. Canned 'pumpkin pie mix' is purée pre-mixed with sugar and spices. It weighs close to the same per cup, but using it where a recipe expects plain purée doubles the sweetening. Check the can's front, not just its size.
Homemade purée runs wetter. Purée you make from a roasted pumpkin usually carries more free water than the dense canned kind, so a cup of it can bake up looser. Drain it in a sieve for half an hour and it approaches the canned standard the 245-gram figure assumes.

About 1¾ cups. The can holds 425 grams and a cup is 245 grams (425 ÷ 245 ≈ 1.73). The persistent myth that the can is 2 cups leaves pies 65 grams short.
