Coil Length Calculator

Formula

To calculate the coil length:

\[ CL = (OD - WD) \times \pi \]

Where:

\(\text{CL}\) is the Coil Length (length per coil)
\(OD\) is the Outer Diameter
\(WD\) is the Wire Diameter
\(\pi\) is the mathematical constant Pi (approximately 3.14159)

Coil Length

The Coil Length refers to the length of wire needed to form one complete coil. This length is determined by subtracting the wire diameter from the outer diameter of the coil and then multiplying the result by Pi (π). This calculation is crucial in various applications, including electronics and mechanical design, where precise dimensions are essential for performance and fitting.

Example Calculation 1

Let's assume the following values:

Outer Diameter (\(OD\)) = 10 units
Wire Diameter (\(WD\)) = 2 units

Using the formula:

\[ CL = (10 - 2) \times \pi = 8 \times \pi \approx 25.13 \text{ units} \]

The coil length is approximately 25.13 units.

Example Calculation 2

Let's assume the following values:

Outer Diameter (\(OD\)) = 20 units
Wire Diameter (\(WD\)) = 5 units

Using the formula:

\[ CL = (20 - 5) \times \pi = 15 \times \pi \approx 47.12 \text{ units} \]

The coil length is approximately 47.12 units.
