A medium zucchini, a cup of sliced summer squash and a cup of cubed butternut squash each have a piece or cup weight printed on their SR Legacy record page. This guide gives twenty such records from the SR Legacy table of USDA FoodData Central: eleven summer squash records (zucchini raw, baby, boiled, frozen and canned, and summer squash of all varieties raw and boiled) and nine winter squash records (winter squash of all varieties raw and baked, and butternut raw, baked and frozen), with the weights printed on their record pages. Pumpkin itself is in our broccoli, pumpkin, turnip and celery guide, kaddu, tinda and parwal on IFCT rows in our parwal, tinda, kathal and kaddu guide and the other gourds in our karela, lauki, turai and bhindi guide. USDA has no ash gourd (petha) record, and IFCT 2017, the Indian Food Composition Tables from ICMR-NIN, has its own rows for ash gourd, pumpkin and tinda, named below and not repeated here.

The short answer

By the SR Legacy records, 1 medium raw zucchini (196 g) is 33.3 kcal, 1 cup of sliced boiled zucchini (180 g) 27.0 kcal, 1 medium raw summer squash of all varieties (196 g) 31.4 kcal, 1 cup of cubed raw butternut squash (140 g) 63.0 kcal, 1 cup of cubed baked butternut squash (205 g) 82.0 kcal and 1 cup of mashed frozen boiled butternut squash (240 g) 93.6 kcal. Our reading: summer squash sits at 14 to 21 kcal per 100 g (29 for the canned Italian style zucchini) and winter squash at 34 to 45 (57 for frozen butternut unprepared), so butternut is more than twice the energy of zucchini by weight; a baked cup of butternut is 205 g against 180 g for a boiled cup of zucchini, so compare the grams, not the word cup.

SR Legacy: per printed portion

Each figure is our arithmetic on exact weights: kcal per 100 g times the grams, divided by 100, with the exact product in the sums line and the result shown to 0.1 with half rounding up. Every weight below is printed on the SR Legacy record page; none is ours. Package labels that carry an ounce or pound size inside the label are shown as printed.

Are ash gourd (petha) and kaddu in these records?

No. A search of the SR Legacy table on 28 Oct 2026 for ash gourd, petha and wax gourd returned no record, so this page gives no USDA figure for ash gourd or petha. IFCT 2017, the Indian Food Composition Tables from ICMR-NIN, has its own rows for ash gourd (D001), pumpkin green (D065) and orange (D066), tinda (D073) and cho-cho-marrow (D038); they are named here and not used, and most of their figures are already on our other guides. The USDA butternut and winter squash rows on this page are the dataset's own and we do not say that they are the same as a kaddu. Pumpkin itself, raw, boiled and canned, is in our broccoli, pumpkin, turnip and celery guide.

Can I log a squash in NYUS?

NYUS is our app. You log foods yourself by searching 8,900+ Indian and global foods or by barcode; log a squash by its cooked weight when you can. NYUS is in early access on Android: 30-day free trial, then plans from ₹499 for one month, paid once with no auto-renewal, no card needed to start.
