Add the total number of wires inside the conduit.

Example:

  • 10 wires

Step 4: Click Calculate

The calculator instantly displays:

  • Fill percentage
  • Safety status

Step 5: Review the Results

If the fill percentage exceeds safe limits, consider using a larger conduit size.


How to Use the Bend Offset Calculator

This section calculates the distance between conduit bends based on offset height and bend angle.

Step 1: Enter Offset Height

Input the required vertical offset in millimeters.

Example:

  • 120 mm

Step 2: Select Bend Angle

Choose the desired conduit bend angle.

Options include:

  • 45°
  • 30°
  • 22.5°
  • 10°

Step 3: Click Calculate

The tool instantly calculates the required bend distance.

Step 4: Use the Measurement

Apply the calculated distance during conduit bending and installation.


How to Use the Pipe Length Calculator

This section estimates the total conduit length required for a project.

Step 1: Enter Number of Conduits

Provide the total quantity of conduits needed.

Example:

  • 12 conduits

Step 2: Enter Length Per Conduit

Add the length of each conduit in meters.

Example:

  • 3 meters

Step 3: Click Calculate

The calculator instantly displays the total required conduit length.

Step 4: Plan Materials

Use the result to estimate material requirements and project costs.


Practical Example 1: Residential Electrical Wiring

Suppose an electrician is wiring a residential building and needs to install multiple wires inside a conduit.
