Hello!

Can someone tell me how to calculate RTD PT100 Temperature from its Resistance. I need the equation for calculating temperature from resistance. I've coded for resistance and it is working properly. I need the equation to get the value of temperature from rtd pt100's resistance.
 

The post asks for the inverse calculation. It can be performed based on a polynominal as well. The fit should be calculated based on the intended accuray and temperature range with the necessary order.

You can use the curve fit feature of a spread sheet calculator like MS Excel to calculate the polynomial coefficients.

Sorry, but I've checked all those links. The quuation I have is giving the right temperature only upto 100 degree C. Any thing above 100 degree C, I'm getting wrong values.
