Specific Weight Calculator

Formula

The formula to calculate the specific weight is:

\[ SPW = \frac{W}{V} \]

Where:

\( SPW \) is the Specific Weight (lbs/ft³)
\( W \) is the Weight (lbs)
\( V \) is the Volume (ft³)

What is Specific Weight?

Specific weight is a measure of the weight of a material per unit volume. It is commonly expressed in pounds per cubic foot (lbs/ft³). This property is important in fields such as engineering, construction, and material science, as it helps in determining how much a certain volume of material will weigh. The specific weight is a crucial factor in designing structures and selecting materials for various applications.

Example Calculation

Let's consider an example:

Weight (W): 1000 lbs
Volume (V): 50 ft³

Using the formula to calculate the Specific Weight (SPW):

\[ SPW = \frac{1000}{50} = 20 \, \text{lbs/ft}^3 \]

This means the specific weight of the material is 20 lbs/ft³.
