Net Weight Calculator

Most states require net weight in both US customary units (ounces or pounds) and metric units (grams) — check your state's exact requirement in its label requirements list.

No. Net weight refers to the product itself, not the box, bag, or container it's sold in. Weigh the product alone, or subtract the empty packaging weight from the total.

A kitchen scale accurate to at least 0.1 oz (or 1 gram) is sufficient for most cottage food products. Set it to ounces or grams depending on which figure you want to enter directly.

For consistency, weigh a representative sample and use that average weight per unit, especially for handmade items where weight naturally varies slightly (cookies, cake pops). Round down slightly if your net weight statement needs to be a guaranteed minimum.

Label accuracy matters for compliance — this tool uses the standard 28.3495 grams per ounce conversion (not a rounded 28.35 or 30g approximation) so your metric net weight is precise.
