Which data is needed to convert weight into volume?

Converting weight into volume relies heavily on the concept of specific gravity, which is a measure of the density of a substance relative to the density of water. Specific gravity indicates how much mass is contained in a given volume for a particular substance. By knowing the specific gravity, one can determine the volume of a certain weight of that substance because it allows for the conversion between mass (weight) and volume based on the relationship defined by the formula:

Volume = Mass / (Specific Gravity × Density of Water)

This conversion is essential in various scientific and nutritional applications where precise measurements are needed, such as in cooking or formulating dietary plans.

Mass alone does not provide the necessary information about how that mass relates to volume without knowledge of density, which is encapsulated in specific gravity. Temperature and pH, while potentially relevant in other contexts such as food safety or nutrient stability, do not have a direct role in the conversion of weight to volume in this instance.
