The specific gravity of water is defined as what value?

The specific gravity of water is defined as a value of 1. Specific gravity is a dimensionless quantity that compares the density of a substance to the density of water at a specified temperature (typically 4 degrees Celsius, where water is most dense). Since water has a density of approximately 1 gram per cubic centimeter, substances with a specific gravity greater than 1 are denser than water, while those with a specific gravity less than 1 are less dense. This fundamental property is crucial in various fields, including safety and engineering, as it helps in identifying material behavior in different environments. Understanding this concept is essential for making informed decisions regarding material selection and safety assessments.
