About this calculator
US standard can sizes are a holdover from canning industry codes. #303 (the most common — tomato sauce, chili, canned vegetables) is 16-17 oz (~2 cups). #10 cans are food-service / restaurant size — 6.5 lb each, used for bulk tomatoes, beans. Modern cans often print net weight in oz/g but the # number persists in older recipes ("a #2 can of tomatoes"). Net weight ≠ drained weight: a #303 can of beans contains ~16 oz total but only ~10 oz drained beans.
Frequently asked
Modern US cans print net weight in oz only. The # designation is mostly archival but still used in older cookbooks and bulk catalogs.
