Everything is ok,except for the fact, that now you saying that is "recommended to convert from resistance to temperature (and not the other way around).... But why is that? I've been previously being doing this and everything seems ok... So why the recommendation, I don't get it... Is it the predicted equation less accurate??

Hi JLuna,

is "recommended to convert from resistance to temperature (and not the other way around).... But why is that?

Usually you measure the resistance of your thermistor and want to calculate the temperature from this value…

The reason I came up with this problem is because:

- Based on a detected temperature I need to be in certain levels of NTC resistance. So my question is, if I use the original structure, been the Resistance values - "x" and the respective temperature values - "f(x)" .... Is there an inconvinience with the calculated Polynomial Fit Curve Equation...??

The polynomial solution should work well both ways.

*(Programming the inverse Stainhart-Hart equation is a bit more tricky).*
