Weight of product contents without packaging. It is not the same as the weight of the entire shipment or the sum of the weight of the active ingredients. In supplements, net weight may also include capsule shells and technological ingredients. The number of capsules, quantity per serving and net weight describe various properties of the packaging, so it is worth reading them together when comparing variants.
What is weighed as content
Net weight describes the quantity of the product without the weight of the packaging. It is not the weight of the entire shipment or the box alone. Depending on the category, there may be a number of capsules, a serving weight or a volume next to it. This data answers various questions. If the cream is given in grams, you should not automatically read the same number of milliliters, because the density would be needed for the conversion. Also in a supplement, the weight of the entire content does not determine the amount of a single active ingredient.
In the case of several packages, it must be determined whether the declaration applies to one piece or the entire set. The price per gram requires the same basis. The weight of a jar, cap or carton should not be added to the net weight, even if these items constitute a significant part of the total weight of the shipment.
Meaning and application
Net weight describes the quantity of the product without packaging, but does not replace serving information. When comparing offers, check whether the declaration concerns a powder, a liquid, a complete set or another form. The number of capsules is yet another parameter.
In practice
Enter the unit and range of the designation. Only then compare prices. For a supplement, also read the daily dose; in cosmetics, method of use. Do not assume that identical net weight provides the same number of uses.
Do not convert grams to milliliters using a fixed rule for all products. Weight and volume are different quantities, and without knowing the properties of the product, such a comparison may be incorrect. The size of the box also does not determine the contents.
