Foodservice can and pack size reference
Identify common foodservice can-size descriptions, then use the actual case label for count, net weight, drained weight, and recipe costing.
Overview
Trade can numbers help identify familiar package formats, but they do not guarantee the exact net weight or drained quantity of every food. Product, pack configuration, and label basis matter. Use the chart as a lookup cue, then cost from the actual invoice and package label. If a recipe uses drained solids, measure or obtain the drained basis rather than substituting the can's gross or net liquid-inclusive amount.
How to read a can or case before costing
- Identify the trade size. Use the chart to recognize a common can format. Treat the listed capacity as approximate, not as a substitute for the label.
- Read the full case configuration. Record the number of containers, size per container, product identity, and the quantity unit. Multiply count by labeled quantity only when both refer to the same basis.
- Choose net or drained quantity. Use net contents for a recipe that uses the contents on that basis. If the recipe uses drained solids, cost the measured or specified drained quantity.
- Convert to the recipe unit. Use an exact same-dimension conversion or a measured ingredient-specific relationship before calculating a used line cost.
Use the package label as the costing source
- Reference Trade description
Approximate can format only.
- Verify Invoice and label
Case count, pack quantity, product, and unit.
- Select Quantity basis
Net contents or measured drained contents.
- Cost Recipe amount
Convert compatible units, then cost the used amount.
Do not substitute one package quantity for another
A case description, a labeled net quantity, and a drained quantity can all be correct while describing different bases.
| Quantity shown | What it describes | When it is useful | Before costing |
|---|---|---|---|
| Trade can size | Common container format | Initial identification and ordering conversation | Confirm actual product label; do not infer exact weight. |
| Case count | Number of containers in a case | Converting one case price to an inner-unit price | Record the actual count of cans or packs. |
| Net contents | Labeled contents, potentially including packing liquid | Recipes using contents on the same net basis | Check unit and product state. |
| Drained quantity | Solid food remaining after draining | Recipes costed on drained solids | Use an explicit label or measured drained amount. |
Common can size descriptions
These common capacities are approximate volume references. A trade size does not establish the net weight, drained weight, or pack count for every product.
| Trade size | Approximate volume |
|---|---|
| No. 10 | 12 to 13 2/3 cups |
| No. 3 cylinder | 5 3/4 cups |
| No. 2 1/2 | 3 1/2 cups |
| No. 2 cylinder | 3 cups |
| No. 2 | 2 1/2 cups |
| No. 300 | 1 3/4 cups |
| No. 2 vacuum | 1 1/2 cups |
| No. 1 picnic | 1 1/4 cups |
Read the actual label
Verify the exact product, count, and quantity on the invoice and package. Use the label's stated unit and decide whether the recipe requires net contents or drained solids.
- Net weight includes the contents described on the label; drained weight describes a different usable state when liquid is removed.
- Record cans or bags per case from the actual supplier specification. A common case pattern is not a universal case count.
- Keep weight ounces (oz) and fluid ounces (fl oz) separate. A can number alone supplies neither a reliable ingredient density nor a usable yield.
Worked example: cost from a stated case label
An illustrative invoice states a case contains 6 cans, each labeled 106 oz net weight, and the case price is $31.80. A recipe uses 10 oz on that same net-weight basis.
Inputs
- Containers per case
- 6 cans
- Labeled net weight per can
- 106 oz
- Case price
- $31.80
- Recipe quantity
- 10 oz
- Case net quantity = 6 × 106 oz = 636 oz.
- Purchase-unit cost = $31.80 ÷ 636 oz = $0.05 per oz.
- Used ingredient cost = $0.05 per oz × 10 oz = $0.50.
- If the recipe uses drained solids, this net-weight calculation is not on the required drained basis.
- Case quantity: 6 cans × 106 oz/can = 636 oz net
Result: $0.50 for 10 oz on the labeled net basis
Keep the case unit cost unrounded through the used-quantity calculation; display the final dollar amount to cents. The case price is illustrative and not a current market quote.
What to record before costing
Retain invoice date, product identity, inner-pack count, quantity per container, and net-versus-drained basis. Use measured yield separately when the purchased form does not match the usable recipe form.
Use the actual label quantity
A trade size is a convenient identifier, not a guarantee of exact weight, drained output, or servings. Record the package configuration and the quantity basis that matches the recipe, then convert or measure only as needed for the chosen calculator.
