The difference between density, specific weight, and specific gravity. Including formulas, definitions, and reference values for common substances.

In fluid mechanics, specific weight represents the force exerted by gravity on a unit volume of a fluid. For this reason, units are expressed as force per unit volume (e.g., N/m 3 or lbf/ft 3).

Nov 10, 2025 · Specific weight is a fundamental property used across physics and engineering, especially for fluids. This property quantifies the weight of a substance relative to the space it …

While density is a measure of how tightly packed the molecules in a substance are, specific weight is a measure of the gravitational force acting on a unit volume of the substance. The …

Specific weight is calculated by dividing a substance’s weight by its volume. For instance, if you know the total weight of a liquid and the space it occupies, you can determine its specific weight.

Nov 11, 2025 · In conclusion, specific weight is defined as the weight per unit volume of a substance. It depends on the density of the fluid and the gravitational acceleration.

Specific weight can be thought of as how much force gravity exerts on a certain volume of material. Objects with higher density will have a higher specific weight, but just because an …

Jun 11, 2025 · Specific weight, also known as weight density, is a fundamental property in fluid mechanics that represents the weight of a fluid per unit volume. It is a crucial parameter in …

Specific Weight, on the other hand, is the weight per unit volume of a material. It takes into account the gravitational force acting on the mass, making it a vector quantity.

The specific weight is the existing relationship between the weight and the volume that occupies a substance in space . It is the weight of a certain amount of substance divided by the volume it …
