trace width

Hello,

I am in the middle of a PCB task and while i was calculating the proper width of the copper i should use for 8 amp PCB using only one layer cooper, i came across the "Temperature Rise" field and didn't know what to fill it out.

Could you help with this guys?

the calculator i am using :

    trace width

    Fill in the current of 8 amps, the maximum temperature rise, and the copper weight. Standard copper weight is 1 oz. Let's put in 8 amps, 20 degrees C, and 1 oz copper. The calculator tells us to use a trace width of 137 mils (that's 0.137") for an external trace or 356 mils for an internal trace.
