Calculation Formula

Wire Length (L) = π * (Outer Diameter + Inner Diameter) / 2 * Number of Active Coils

Where:
π = 3.141592653589793
Outer Diameter = Outer diameter of the spring (mm)
Inner Diameter = Inner diameter of the spring (mm)
Number of Active Coils = Number of coils that contribute to the spring's deflection

How to Use the Calculator

  1. Enter the outer diameter of the spring in millimeters.
  2. Enter the inner diameter of the spring in millimeters.
  3. Enter the number of active coils in the spring.
  4. Click the "Calculate" button to compute the wire length.
  5. The wire length will be displayed in millimeters.

Working Principle

The wire length of a spring is calculated using the formula:

Wire Length (L) = π * (Outer Diameter + Inner Diameter) / 2 * Number of Active Coils

This formula takes into account the circumference of the mean diameter of the spring and multiplies it by the number of active coils to determine the total length of the wire used in the spring.
