NTC Resistance to Temperature
Change the inputs; results update automatically.
Formula
1/T(K) = 1/T0(K) + (1/B) x ln(R / R0)T(°C) = T(K) - 273.15 Worked example
At 10000 Ω, reference resistance 10000 Ω at 25 °C, the result is 25 °C.
Scope and interpretation
The beta and reference values must match the sensor. A different NTC curve can produce a different temperature.
