For those who are playing at home, the non-linear, second-order accurate formula of an industrial-grade platinum resistance thermometer (PT100/PT1000) from 0 °C to 850 °C is, according to IEC 60751:
Bt^2 + At + 1 - \frac{R}{R_0} = 0
in which:
R = \text{measured resistance.} \\
R_0 = 100 \space\Omega, 1000 \space\Omega, \text{etc}. \\
A = 3.9083 \cdot 10^{-3} \degree \mathrm{C}^{-1} \\
B = -5.775 \cdot 10^{-7} \degree \mathrm{C}^{-2}
