Actually, I was wondering if there is any such thing as a square law area any way?I thought the square law area involved the squaring of a decimal amount and ending up with less than you started with (eg. 0.5*0.5 = 0.25).

But... you are already starting with decimal amounts (ie. mA versus Volts or mV's which is the usual graph "Y" axis).

If the axes were amps and volts, then squaring mv's or mA's should give square law values over the whole range of the "usual" graph.

Drawing a graph using uA's versus mV's/uV's as the "units" would give result at a different "square law point".

ie. Is there any real square law area at all?

Depends on the units used, and, what we actually define (arbitrarily) a unit to be?

(Is an amp really a "natural" unit or do we just say it is in our scheme of things).

Rambling a bit, but you should get my drift.
