Specific Weight Calculator


Calculating specific weight can be crucial in various engineering and scientific applications, where understanding the weight of a substance per unit volume is necessary. With the aid of a simple calculator, this task becomes more manageable. Below, we provide a guide on using a specific weight calculator, along with its formula, an example solve, and frequently asked questions.

How to Use

To utilize the specific weight calculator, input the required values into the designated fields. Then, click on the “Calculate” button to obtain the result.


The formula to calculate specific weight is:


  • Weight(W) is the total weight of the substance in Newtons (N).
  • Volume(V) is the total volume of the substance in cubic meters (m³).

Example Solve

Suppose we have a substance with a weight of 500 N and a volume of 2 m³. Let’s calculate its specific weight:


Q: What is specific weight?

A: Specific weight, also known as unit weight, is the weight per unit volume of a substance.

Q: What are the units of specific weight?

A: Specific weight is typically measured in Newtons per cubic meter (N/m³) or pounds-force per cubic foot (lb/ft³).

Q: How is specific weight different from density?

A: Specific weight represents the weight per unit volume of a substance, while density represents the mass per unit volume.

Q: Can specific weight be negative?

A: No, specific weight cannot be negative as it represents the weight of a substance, which is always positive or zero.


In conclusion, the specific weight calculator simplifies the process of determining the weight per unit volume of a substance. By following the provided guide and using the calculator, engineers, scientists, and students can efficiently perform specific weight calculations for various materials.
