Trace Width

(1/2) > >>

Hi every one,

I design a PCB which power trace should be cable to carry 16A. I found two online calculators claims that their calculations based on IPC-2221 standard.
However inserting the same parameters in both calculators there is significant deviation between the results

Calculator 1
https://www.4pcb.com/trace-width-calculator.html

Calculator 2
https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-pcb-trace-width

I attach the screenshots from the results

Thanks in advance

Hi.
In your digikey screenshot you screwed up the unit of measure (mil vs mm). I tried with mms and the results are comparable

The PCB looks like the attached

It is correct the traces to be wider than the through hole plated pads?
