By law, we are required to list the "ounces" and "grams," which are measures of weight, not measures of volume, on the food label. Because the formula is made from real food, its density can vary and, as such, so can the volume of the formula in each pouch. Rest assured, each pouch of Liquid Hope and Nourish contains 341 grams as measured on a gram scale.
This is a confusing subject for most but first. All nutritional information as stated on our website and packaging is correct, it is calculated and tested per pouch and the most accurate measure is 341 grams which is what our manufacturers use as gauge of measurement and what their scales are set to. Any below is rejected.
The conversation of weight is complex one due to the fact that our product, per food labeling laws, has to show 12 oz on the label. However, our products are not fluid ounces as most people expect, due to the viscosity. A glass measuring cup or syringe with ounce measurements is designed to only fluid ounces. Our product due to not being "fluid" or thin as water will only show 10 ounces.
We have done our best to offer accurate ML measures as a courtesy knowing that RDs are used to working with this measuring system.
Why are there variables in ML from pouch to pouch?
When it comes to measuring solids and liquids, weight (gram) is generally considered as more accurate than volume (Ml). This is because the weight of a substance on Earth will remain constant even if its surrounding condition changes (e.g. if it gets hotter or colder). On the other hand, the amount of space (volume) occupied by a substance – especially if it is a liquid – can be affected by things like changes in temperature without the substance changing its form (i.e. whilst remaining a liquid still).
