Enter your trace width, trace thickness, trace length, and trace resistivity into the calculator to determine the trace resistance.

## Trace Resistance Calculation Formula

The following formula is used to calculate the trace resistance from your inputs.

Trace Resistance = (Trace Resistivity * Trace Length) / (Trace Width * Trace Thickness)

Variables:

- Trace Resistance is the resistance of the trace (ohms)
- Trace Resistivity is the resistivity of the trace material (ohm/mil²)
- Trace Length is the length of the trace (inches)
- Trace Width is the width of the trace (mil)
