The density of a solid or liquid material devided by the density of water is called?
What is Hvac?
HVAC is the certificate you're working for, right, Kishon?
Heating, Ventilation, and Air Conditioning
But your school subject is science.
The term you are referring to is called the specific gravity of a material. To calculate the specific gravity, you divide the density of the material by the density of water. The formula for specific gravity is as follows:
Specific Gravity = Density of Material / Density of Water
The density of water is generally taken to be 1 gram per cubic centimeter (1 g/cm³) or 1000 kilograms per cubic meter (1000 kg/m³). So, if you know the density of a solid or liquid material, you can easily calculate its specific gravity by dividing its density by 1 g/cm³ or 1000 kg/m³, depending on the units used for the material's density.
