Steinhart–Hart Equation

Equation:
1/T = A + B·ln(R) + C·[ln(R)]³

Coefficients:

  • A = 0.001763
  • B = 0.0002380
  • C = 1.83×10⁻⁷

Where:

  • T = temperature in Kelvin
  • R = resistance in ohms
  • To convert to °C: T(°C) = T(K) − 273.15

Measured Test Values

Temperature (°C) Resistance (Ω)
100.0 43.5
79.3 95.1
59.8 155.2
44.7 287.9
1.55 1922
