Pt100 Resistance to Temperature
Change the inputs; results update automatically.
Formula
T(°C) = (R - 100) / 0.385 (Linear approximation)t ≥ 0 °C için nominal eğri: R(t) = R₀(1 + A·t + B·t²); t < 0 için C terimi eklenir. Worked example
119.40 Ω gives (119.40 − 100)/0.385 ≈ 50.39 °C with this linear model.
Scope and interpretation
This calculator uses a linear approximation. Use the appropriate sensor curve for precision work and account for lead resistance.
