Coil springs are essential components in various industries and applications, and knowing their weight is crucial for design and engineering purposes. The Coil Spring Weight Calculator is a simple tool that helps you determine the weight of a coil spring based on key parameters. In this article, we will provide you with the code for this calculator and a guide on how to use it effectively.

## Formula

The weight of a coil spring can be calculated using the following formula:

*Weight (lbs) = π * (Wire Diameter / 2)^2 * Mean Diameter * Number of Coils * Coil Length * 0.000011342*

Where:

*π*is the mathematical constant pi (approximately 3.14159).*Wire Diameter*is the diameter of the wire used in the coil (in inches).*Mean Diameter*is the average diameter of the coil (in inches).*Number of Coils*is the total number of coils in the spring.*Coil Length*is the length of the coil spring (in inches).

## How to Use

Using the Coil Spring Weight Calculator is easy and straightforward:

- Enter the
*Number of Coils*in the appropriate field. - Input the
*Wire Diameter*(in inches). - Provide the
*Mean Diameter*(in inches). - Specify the
*Coil Length*(in inches). - Click the “Calculate” button.
- The result will appear below, displaying the weight of the coil spring in pounds (lbs).

## Example

Let’s consider an example to better understand how the Coil Spring Weight Calculator works:

- Number of Coils: 10
- Wire Diameter: 0.2 inches
- Mean Diameter: 2 inches
- Coil Length: 8 inches

After entering these values and clicking “Calculate,” the calculator will display the result:

*Result: 8.98 lbs*

This means that a coil spring with the given parameters has an approximate weight of 8.98 pounds.
