Calculate the resistance of your PT-100 RTD sensor based on temperature or find the temperature from a measured resistance. This interactive calculator supports Celsius (°C), Fahrenheit (°F), and Kelvin (K), and lets you customize sensor parameters like R₀ and the temperature coefficient α.
RTD Calculator (PT-100)
Formula Used: RT = R₀ (1 + α × T)
Temperature → Resistance
Resistance → Temperature
This calculator uses a linear RTD approximation and is intended for educational and preliminary calculations. For precise industrial applications, refer to IEC 60751 Callendar–Van Dusen equations.
