Track Width Calculator (mm)

Units: mm/mil

 

Track width at top 

Copper thickness 

Temperature rise 


0.00 Amps

Track width at bottom 

Track width at Top:

This value dictates the width of the track at the top and allows for over etching or etching issues. If this is unknown then this value should be the same as the track width value.

Track Width:

This should contain the width value of the track whose current capacity you are working out.

Copper Thickness:

This is normally specified in ounces per square foot. The list below will show you the most common ones.

Copper weights:

0.25OZ = 0.00889mm

0.5OZ = 0.01778mm

1OZ = 0.03556mm

2OZ =0.07112mm

3OZ = 0.10668mm

4OZ = 0.14224mm

 

Temperature rise above ambient:

This value should be provided in °C.

When the above values are inserted, pressing the submit button will inform you of the amperage that the track should carry.
