# Coil Diameter Calculator

## How to Use the Coil Diameter Calculator:

To utilize the Coil Diameter Calculator effectively, follow these steps:

- Input the coil length in millimeters, along with the number of turns and wire diameter.
- Select the appropriate measurement units for coil length and wire diameter from the dropdown options (e.g., millimeters, centimeters, inches, feet, or meters).
- Click the “Calculate Coil Diameter” button.
- The calculator will provide the accurate coil diameter measurement in millimeters as a result.

## Formula to calculate Coil diameter

### The coil diameter is calculated using the formula:

\[ CD = \frac{CL}{N} - WD \]Where:

- \( CD \) is the coil diameter.
- \( CL \) is the coil length.
- \( N \) is the number of turns.
- \( WD \) is the wire diameter.

## Examples

Given a coil with a length (\(CL\)) of 200 millimeters, 8 turns (\(N\)), and a wire diameter (\(WD\)) of 5 millimeters, what is the coil diameter (\(CD\))? Use the Coil Diameter Calculator formula.

**Answer:**

The coil diameter (\(CD\)) is calculated using the formula:

\[ CD = \frac{CL}{N} - WD \]Substituting the given values:

\[ CD = \frac{200}{8} - 5 = 20 - 5 = 15 \text{ millimeters} \]Therefore, the coil diameter is 15 millimeters.

## What is Coil Diameter:

The coil diameter refers to the measurement across the circular cross-section of a coil, often expressed in millimeters (mm). It represents the distance from one side of the coil to the opposite side, passing through the center. The Coil Diameter Calculator is a tool designed to compute this value based on inputs such as coil length, number of turns, and wire diameter.
