About

How it works

Given the wire diameter and weight, the calculator determines the length using the material density.

Formula:
Length = Weight / (Density × π (d/2)²)

Supported Gauge Standards

BWG – Birmingham Wire Gauge
AWG – American Wire Gauge
SWG – Standard Wire Gauge (British)

Quick Tips

Click any gauge button to instantly set the diameter.
Switch between gauge systems using the tabs.
Enter a custom density if your material isn't listed.
